Input: Consider 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

Input: Consider Input: Context: Marcus Antonius Primus ( 30/35 -- after 81 AD ) was a general of the Roman Empire . Primus was born at Tolosa ( Toulouse ) in Gaul . During the reign of Nero , he was resident in Rome and a member of the Senate , from which he was expelled for conspiring to forge a will with Valerius Fabianus , and was banished from the city . He was subsequently reinstated by Galba , and placed in command of the Legio VII Galbiana in Pannonia . During the civil war , Primus was one of Vespasian 's strongest supporters . Advancing into Italy , he gained a decisive victory over the Vitellians at Bedriacum in October 69 , and on the same day stormed and set fire to Cremona . He then crossed the Apennines , and made his way to Rome , into which he forced an entrance after considerable opposition . Vitellius was seized and put to death . For a few days , Primus was virtually ruler of Rome , and the Senate bestowed upon him the rank and insignia of a consul , but on the arrival of Licinius Mucianus , he left Rome . Primus must have been alive during the reign of Domitian , since four epigrams of Martial are addressed to him . Tacitus describes him as brave in action , ready of speech , clever at bringing others into odium , powerful in times of civil war and rebellion , greedy , extravagant , in peace a bad citizen , in war an ally not to be despised ., Constantinople  was the capital city of the Roman/Byzantine Empire (3301204 and 12611453), and also of the brief Latin (12041261), and the later Ottoman (14531923) empires. It was reinaugurated in 324 AD from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, and dedicated on 11 May 330 AD., Rome is a city and special "comune" (named "Roma Capitale") in Italy. Rome is the capital of Italy and of the Lazio region. With 2,870,336 residents in , it is also the country's largest and most populated "comune" and fourth-most populous city in the European Union by population within city limits. The Metropolitan City of Rome has a population of 4.3 million residents. The city is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of Tiber river. The Vatican City is an independent country geographically located within the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states. , The Roman Empire (Koine and Medieval Greek:   , tr. ) was the post-Roman Republic period of the ancient Roman civilization, characterized by government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, Africa and Asia. The city of Rome was the largest city in the world BC AD, with Constantinople (New Rome) becoming the largest around 500 AD, and the Empire's populace grew to an estimated 50 to 90 million inhabitants (roughly 20% of the world's population at the time). The 500-year-old republic which preceded it was severely destabilized in a series of civil wars and political conflict, during which Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and executions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavian's power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title "Augustus", effectively marking the end of the Roman Republic., The Roman Republic was the era of ancient Roman civilization beginning with the overthrow of the Roman Kingdom, traditionally dated to 509 BC, and ending in 27 BC with the establishment of the Roman Empire. It was during this period that Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world., The Battle of Actium was the decisive confrontation of the Final War of the Roman Republic, a naval engagement between Octavian and the combined forces of Mark Antony and Cleopatra on 2 September 31 BC, on the Ionian Sea near the promontory of Actium, in the Roman province of Epirus Vetus in Greece. Octavian's fleet was commanded by Marcus Vipsanius Agrippa, while Antony's fleet was supported by the power of Queen Cleopatra of Ptolemaic Egypt., Augustus (23 September 63 BC  19 August 14 AD) was the founder of the Roman Principate and considered the first Emperor, controlling the Roman Empire from 27 BC until his death in AD 14., Gaius Julius Caesar (13 July 100 BC  15 March 44 BC), known as Julius Caesar, was a Roman politician, general, and notable author of Latin prose. He played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire., The Roman Senate was a political institution in ancient Rome. It was one of the most enduring institutions in Roman history, being established in the first days of the city (traditionally founded in 753 BC). It survived the overthrow of the kings in 509 BC, the fall of the Roman Republic in the 1st century BC, the division of the Roman Empire in 395 AD, the fall of the Western Roman Empire in 476 AD, and the barbarian rule of Rome in the 5th, 6th, and 7th centuries., Cleopatra VII Philopator (69  August 12, 30 BC), known to history simply as Cleopatra, was the last active pharaoh of Ptolemaic Egypt, briefly survived as pharaoh by her son Caesarion. After her reign, Egypt became a province of the recently established Roman Empire., Marcus Antonius (Latin: ; January 14, August 1, 30 BC), commonly known in English as Mark or Marc Antony, was a Roman politician and general who played a critical role in the transformation of the Roman Republic from an oligarchy into the autocratic Roman Empire., Subject: marcus antonius primus, Relation: date_of_death, Options: (A) 1 (B) 100 (C) 12 (D) 1204 (E) 1261 (F) 13 (G) 14 (H) 1453 (I) 19 august 14 (J) 1923 (K) 2 (L) 20 (M) 23 (N) 27 (O) 30 (P) 330 (Q) 336 (R) 395 (S) 44 (T) 50 (U) 500 (V) 509 (W) 69 (X) 753 (Y) 90

It extends between Finland (to the north) and Estonia (to the south) all the way to Saint Petersburg in Russia, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbours are located farthest in, near Saint Petersburg (including Primorsk). As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf., Uusimaa or Nyland (both names mean new land) is a region in Finland. It borders the regions Southwest Finland, Tavastia Proper, Päijänne Tavastia and Kymenlaakso.

A peninsula with the Gulf of Finland to the south and the Gulf of Bothnia to the west, the country has land borders with Sweden to the northwest, Norway to the north, and Russia to the east. Estonia is south of the country across the Gulf of Finland. Finland is a Nordic country situated in the geographical region of Fennoscandia, which also includes Scandinavia. Finland's population is 5.5 million (2014), staying roughly on the same level over the past two decades. The majority of the population is concentrated in the southern region. In terms of area, it is the eighth largest country in Europe and the most sparsely populated country in the European Union., Helsinki  is the capital and largest city of Finland. It is in the region of Uusimaa, in southern Finland, on the shore of the Gulf of Finland. Helsinki has a population of , an urban population of 1,214,210, and a metropolitan population of over 1.4 million, making it the most populous municipality and urban area in Finland. Helsinki is located some north of Tallinn, Estonia, east of Stockholm, Sweden, and west of Saint Petersburg, Russia. Helsinki has close historical connections with these three cities., MS Celestyal Olympia is a cruise ship owned by the Cyprus - based Celestyal Cruises , formally Louis Cruise Lines . In April 2012 she was named Louis Olympia after operating as the Thomson Destiny for Thomson Cruises . She was built in 1982 at Wärtsilä Hietalahti shipyard in Helsinki , Finland for Royal Caribbean Cruise Lines as MS Song of America . Between 1999 and 2004 she sailed for Sun Cruises as MS Sunbird . She was previously under charter to the United Kingdom - based Thomson Cruises up until April 2012 as the MS Thomson Destiny . She has since sailed for Louis Cruises as MS Louis Olympia , and as MS Celestyal Olympia since 2014 ., Royal Caribbean International is a cruise line brand founded in Norway and based in Miami, Florida, United States. It is owned by Royal Caribbean Cruises Ltd. , the line operated 23 ships, had three additional ships on order, and controlled 17 percent of the cruise market worldwide. All ships under the Royal Caribbean International brand have names ending with "of the Seas" (e.g. ) a practice which began in 1991. Sister brands owned by Royal Caribbean Cruises Ltd. are Celebrity Cruises, Azamara Cruises, Pullmantur Cruises and CDF Croisières de France., Sweden, officially the Kingdom of Sweden (Swedish: ), is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund. At , Sweden is the third-largest country in the European Union by area, with a total population of 10.0 million. Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas., Thomson Cruises is a British cruise line operated by Thomson, that offers cruises around Europe with ships from Louis Cruise Lines, Royal Caribbean International and Holland America Line., Holland America Line is an American/British owned cruise line; a subsidiary of Carnival Corporation & plc.
