Information: - 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. After reading the paragraphs above, we are interested in knowing the entity with which 'finite impulse response' exhibits the relationship of 'subclass of'. Find the answer from the choices below.

Question: Information: - Sara Warneke (2 June 1957 27 September 2011), better known by her pen name Sara Douglass, was an Australian fantasy writer who lived in Hobart, Tasmania. - Fantasy is a fiction genre set in an imaginary universe, often but not always without any locations, events, or people from the real world. Most fantasy uses magic or other supernatural elements as a main plot element, theme, or setting. Magic and magical creatures are common in many of these imaginary worlds. Fantasy is generally distinguished from the genres of science fiction and horror by the expectation that it steers clear of scientific and macabre themes, respectively, though there is a great deal of overlap between the three, all of which are subgenres of speculative fiction. - Sinner is the first novel in The Wayfarer Redemption Trilogy by Sara Douglass . In the United States it is also considered the fourth in The Wayfarer Redemption sextet . It is followed by Pilgrim and concludes in Crusader . - Tasmania (abbreviated as Tas and known colloquially as "Tassie") is an island state of the Commonwealth of Australia. It is located to the south of the Australian mainland, separated by Bass Strait. The state encompasses the main island of Tasmania, the 26th-largest island in the world, and the surrounding 334 islands. The state has a population of around 518,500, just over forty percent of which resides in the Greater Hobart precinct, which forms the metropolitan area of the state capital and largest city, Hobart. - Wayfarer Redemption is the name of two trilogies that were released as a single six-book series in the U.S. by fantasy author Sara Douglass, and subdivided into two trilogies: the Axis trilogy, and the Wayfarer Redemption trilogy. This sequence is followed by the Darkglass Mountain trilogy. - Hobart is the capital and most populous city of the Australian island state of Tasmania. It is the least populated state capital in Australia. Founded in 1803 as a penal colony, Hobart is Australia's second oldest capital city after Sydney, New South Wales. The city is located in the state's south-east on the estuary of the Derwent River, making it the most southern of Australia's capital cities. Its harbour forms the second-deepest natural port in the world. After reading the paragraphs above, we are interested in knowing the entity with which 'sinner ' exhibits the relationship of 'series'. Find the answer from the choices below. Choices: - 2 - fantasy - fiction - populous - the axis trilogy - the real world - the state - universe
Answer:
the axis trilogy
