Example Input: Context: In signal processing, the impulse response, or impulse response function (IRF), of a dynamic system is its output when presented with a brief input signal, called an impulse. More generally, an impulse response is the reaction of any dynamic system in response to some external change. In both cases, the impulse response describes the reaction of the system as a function of time (or possibly as a function of some other independent variable that parameterizes the dynamic behavior of the system)., In signal processing, a digital filter is a system that performs mathematical operations on a sampled, discrete-time signal to reduce or enhance certain aspects of that signal. This is in contrast to the other major type of electronic filter, the analog filter, which is an electronic circuit operating on continuous-time analog signals., Infinite impulse response (IIR) is a property applying to many linear time-invariant systems. Common examples of linear time-invariant systems are most electronic and digital filters. Systems with this property are known as "IIR systems" or "IIR filters", and are distinguished by having an impulse response which does not become exactly zero past a certain point, but continues indefinitely. This is in contrast to a finite impulse response (FIR) in which the impulse response "h"("t") "does" become exactly zero at times "t" > "T" for some finite "T", thus being of finite duration., In signal processing , a finite impulse response ( FIR ) filter is a filter whose impulse response ( or response to any finite length input ) is of finite duration , because it settles to zero in finite time . This is in contrast to infinite impulse response ( IIR ) filters , which may have internal feedback and may continue to respond indefinitely ( usually decaying ) . The impulse response ( that is , the output in response to a Kronecker delta input ) of an Nth - order discrete - time FIR filter lasts exactly N + 1 samples ( from first nonzero element through last nonzero element ) before it then settles to zero . FIR filters can be discrete - time or continuous - time , and digital or analog ., Information is that which informs. In other words, it is the answer to a question of some kind. It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer., Signal processing is an enabling technology that encompasses the fundamental theory, applications, algorithms, and implementations of processing or transferring information contained in many different physical, symbolic, or abstract formats broadly designated as "signals". It uses mathematical, statistical, computational, heuristic, and linguistic representations, formalisms, and techniques for representation, modelling, analysis, synthesis, discovery, recovery, sensing, acquisition, extraction, learning, security, or forensics., Subject: finite impulse response, Relation: subclass_of, Options: (A) being (B) case (C) change (D) duration (E) electronic circuit (F) electronic filter (G) event (H) feedback (I) filter (J) heuristic (K) information (L) invariant (M) property (N) question (O) representation (P) security (Q) signal (R) time (S) type
Example Output: electronic filter

Example Input: Context: His Dark Materials is an epic trilogy of fantasy novels by Philip Pullman consisting of "Northern Lights" (1995, published as "The Golden Compass" in North America), "The Subtle Knife" (1997), and "The Amber Spyglass" (2000). It follows the coming of age of two children, Lyra Belacqua and Will Parry, as they wander through a series of parallel universes. The three novels have won a number of awards, most notably the 2001 Whitbread Book of the Year prize, won by "The Amber Spyglass". "Northern Lights" won the Carnegie Medal for children's fiction in the UK in 1995. The trilogy took third place in the BBC's Big Read poll in 2003., Lyra 's Oxford is a short book by Philip Pullman depicting an episode involving the heroine of His Dark Materials , Pullman 's best - selling trilogy . Lyra 's Oxford is set when Lyra Silvertongue is 15 , two years after the end of the trilogy . It was released to quench the thirst of fans of the trilogy while they wait for the unspecified release of The Book of Dust , and also to expand upon Pullman 's themes from the trilogy . The book consists mainly of an illustrated short story , '' Lyra and the Birds '' . A fold - out map of '' Oxford by Train , River and Zeppelin '' is bound in the book , a fictional map of the Oxford that exists in Lyra 's world . It also includes some advertisements for books and travellers ' catalogues . Two pages from a Baedeker published in Lyra 's world ( including entries for the Eagle Ironworks , the Oxford Canal , the Fell Press and the Oratory of St Barnabas the Chymist , all in the Jericho area of Oxford ) , a postcard from the character Mary Malone , and a brochure for the cruise ship Zenobia are also included . Pullman compares the movement of these objects to particles in a cloud chamber . The idea is that they have floated accidentally through an inter-world window . The postcard contains four images of significant sites in the His Dark Materials trilogy : the physics lab in which Mary Malone works , the house occupied by Lord Boreal , the row of hornbeam trees where Will first discovered a window between the worlds , and the bench where Lyra and Will have pledged to visit each other at least in spirit once a year . The preface by Pullman begins : '' This book contains a story and several other things . The other things might be connected with the story , or they might not ; they might be connected to stories that have n't appeared yet . It 's hard to tell . '', Lyra Belacqua , also known as Lyra Silvertongue, is the heroine of Philip Pullman's "His Dark Materials" trilogy. Lyra is a young girl who inhabits a universe parallel to our own. Brought up in the cloistered world of Jordan College, Oxford, she finds herself embroiled in a cosmic war between Lord Asriel on the one side, and the first angel to come into being, called The Authority, and his Regent, called Metatron, on the other., Philip Pullman CBE, FRSL (born 19 October 1946) is an English writer. He is the author of several best-selling books, most notably the fantasy trilogy "His Dark Materials" and the fictionalised biography of Jesus, "The Good Man Jesus and the Scoundrel Christ". In 2008, "The Times" named Pullman one of the "50 greatest British writers since 1945". In a 2004 poll for the BBC, Pullman was named the eleventh most influential person in British culture., Jesus (; c. 4BC c. AD30/33), also referred to as Jesus of Nazareth or Jesus Christ, was a Jewish preacher and religious leader who became the central figure of Christianity. Christians believe him to be the Son of God and the awaited Messiah (Christ) prophesied in the Old Testament.
Virtually all modern scholars of antiquity agree that Jesus existed historically, although the quest for the historical Jesus has produced little agreement on the historical reliability of the Gospels and on how closely the biblical Jesus reflects the historical Jesus. Jesus was a Galilean Jew who was baptized by John the Baptist and subsequently began his own ministry, preaching his message orally and often being referred to as "rabbi". He was arrested and tried by the Jewish authorities, and was crucified by the order of Pontius Pilate, the Roman prefect. Jesus debated fellow Jews on how to best follow God, performed healings, taught in parables and gathered followers. After his death, his followers believed he rose from the dead, and the community they formed eventually became the Christian Church., The Subtle Knife, the second book in the "His Dark Materials" series, is a young-adult fantasy novel written by Philip Pullman and published in 1997. The novel continues the adventures of Lyra Belacqua as she investigates the mysterious Dust phenomenon and searches for her father. Will Parry is introduced as a companion to Lyra, and together they explore the new realms to which they have both been introduced., The Book of Dust is a forthcoming novel by Philip Pullman. It will be a companion novel to the "His Dark Materials" trilogy, and will feature Lyra Belacqua as a main character. Initially, Pullman said that the story will take place two years after the events of "Lyra's Oxford" and will tie into that book, with Lyra being "about sixteen." He has since said "it might be in two volumes and I think one might take place in the time before His Dark Materials and the other might take place afterwards." The book will also be "about Dust," and will address the lack of positive portrayals of religion in the "His Dark Materials" books, although it will not be a continuation of the trilogy., Subject: lyra's oxford, Relation: characters, Options: (A) character (B) death (C) lyra belacqua
Example Output: lyra belacqua

Example Input: Context: Nafplio is a seaport town in the Peloponnese in Greece that has expanded up the hillsides near the north end of the Argolic Gulf. The town was an important seaport held under a succession of royal houses in the Middle Ages as part of the lordship of Argos and Nauplia, held initially by the de la Roche following the Fourth Crusade before coming under the Republic of Venice and, lastly, the Ottoman Empire. The town was the capital of the First Hellenic Republic and of the Kingdom of Greece, from the start of the Greek Revolution in 1821 until 1834. Nafplio is now the capital of the regional unit of Argolis., The Argolic Gulf (also "Gulf of Argolis" or "Gulf of Nafplio") is a gulf of the Aegean Sea off the east coast of the Peloponnese, Greece. It is about 50km long and 30km wide. Its main port is Nafplio, at its northwestern end. At the entrance to the gulf is the island Spetses. This gulf and its islands are sometimes combined with the Saronic Gulf and Saronic Islands, with the result called the Argo-Saronic Gulf and the Argo-Saronic Islands. It is surrounded by two regional units: Arcadia to the southwest and Argolis to the north and east. The river Inachos drains into the Argolic Gulf near Nea Kios. The main islands in the gulf are Psili, Plateia and Bourtzi, a small island with a Venetian fortress that protects the port of Nafplio. The surrounding mountains protect it from the strong summer Meltemi wind., The Ottoman Empire ('; Modern Turkish: ' or '), also known as the Turkish Empire, Ottoman Turkey, was an empire founded at the end of the thirteenth century in northwestern Anatolia in the vicinity of Bilecik and Sout by the Oghuz Turkish tribal leader Osman. After 1354, the Ottomans crossed into Europe, and with the conquest of the Balkans the Ottoman Beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror., The First Hellenic Republic is a term used to refer to the provisional Greek state during the Greek War of Independence against the Ottoman Empire. It is a purely historiographical term, highlighting the constitutional and democratic nature of the revolutionary regime prior to the establishment of the independent Kingdom of Greece, and associating this period of Greek history with the later Second and Third republics., Greece (' ), officially the Hellenic Republic (Greek: ' ), historically also known as Hellas ("" ), is a country in southeastern Europe.
Greece's population is approximately 10.955 million as of 2015. Athens is the nation's capital and largest city, followed by Thessaloniki., The Peloponnese or Peloponnesus ("Peloponnsos"), is a peninsula and geographic region in southern Greece. It is separated from the central part of the country by the Gulf of Corinth. During the late Middle Ages and the Ottoman era, the peninsula was known as the Morea, a name still in colloquial use in its demotic form ()., The castle of Bourtzi ( Greek : , from Ottoman Turkish - burc meaning '' tower '' ; formerly , Kasteli ) is located in the middle of the harbour of Nafplio . The Venetians completed its fortification in 1473 to protect the city from pirates and invaders from the sea . The Greeks regained it from the Turks on June 18 , 1822 , from where they assisted in the siege of Nafplio . Until 1865 it served as a fortress . It was then transformed into residence of the executioners of convicts from the castle of Palamidi . From 1930 to 1970 , it served as a hotel . Since then , it is mainly a tourist attraction hosting occasionally parts of the Summer Music Festival ., The Kingdom of Greece (Greek: , "Vasileion ts Ellados") was a state established in 1832 at the Convention of London by the Great Powers (the United Kingdom, France and the Russian Empire). It was internationally recognized by the Treaty of Constantinople, where it also secured full independence from the Ottoman Empire. This event also marked the birth of the first, fully independent, Greek state since the fall of the Byzantine Empire to the Ottomans in the mid-15th century., Argolis or the Argolid ("Argolida", ; "Argolis" in ancient Greek and Katharevousa) is one of the regional units of Greece. It is part of the region of Peloponnese, situated in the eastern part of the Peloponnese peninsula and part of the tripoint area of Argolis, Arcadia and Corinthia. Much of the territory of this region is situated in the Argolid Peninsula., The Acronauplia (, "Inner Castle") is the oldest part of the city of Nafplion in Greece. Until the thirteenth century, it was a town on its own. The arrival of the Venetians and the Franks transformed it into part of the town fortifications. Later, part of it was used as a prison until the Greek government decided that the view provided from its location would benefit the local tourism and built a hotel complex which still stands there today., Argos (Modern Greek: ; Ancient Greek: ) is a city in Argolis, Peloponnese, Greece and one of the oldest continuously inhabited cities in the world. It is also a former bishopric and present Latin Catholic titular see. It is the biggest town in Argolis and a major center for the area.
Since the 2011 local government reform it has been part of the municipality of Argos-Mykines, of which it is a municipal unit. The municipal unit has an area of 138.138 km. It is from Nafplion, which was its historic harbour. A settlement of great antiquity, Argos has been continuously inhabited as at least a substantial village for the past 7,000 years. The city is a member of the Most Ancient European Towns Network., Palamidi is a fortress to the east of the Acronauplia in the town of Nafplio in the Peloponnese region of southern Greece. Nestled on the crest of a 216-metre high hill, the fortress was built by the Venetians during their second occupation of the area (16861715)., Subject: bourtzi , Relation: located_on_terrain_feature, Options: (A) aegean sea (B) balkans (C) europe (D) france (E) greece (F) peloponnese
