[Q]: 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

[Q]: Context: McLaren Racing Limited, competing as McLaren Honda, is a British Formula One team based at the McLaren Technology Centre, Woking, Surrey, England. McLaren is best known as a Formula One constructor but has also competed in and won the Indianapolis 500 and the Canadian-American Challenge Cup (Can-Am). The team is the second oldest active team after Ferrari. They are one of the most successful teams in Formula One history, having won 182 races, 12 drivers' championships and eight constructors' championships. The team is a wholly owned subsidiary of McLaren Technology Group., The 2001 Formula One season was the 52nd season of FIA Formula One racing. It featured the FIA Formula One World Championship which commenced on 4 March 2001 and ended on 14 October after seventeen races. Michael Schumacher won the Drivers' title with a record margin of 58 points, after achieving nine victories and five second places and Ferrari won the Constructors' award. The season marked the reintroduction of traction control, with the FIA permitting its use starting at the Spanish Grand Prix. Traction control had been banned since . Schumacher also broke the all-time Formula One Grand Prix wins record during the season, scoring his 52nd win in Belgium., David Marshall Coulthard, (born 27 March 1971), known as DC, is a British former Formula One racing driver turned presenter, commentator and journalist. He was runner-up in the 2001 Formula One World Drivers' Championship, driving for McLaren., Mika Pauli Häkkinen (born 28 September 1968), nicknamed ""the Flying Finn"", is a Finnish former professional racing driver. He was the 1998 and 1999 Formula One World Champion, driving for McLaren and has been ranked among the greatest Formula One drivers in various motorsport polls. Häkkinen currently works in driver management and is a brand ambassador for various companies., Formula One (also Formula 1 or F1 and officially the FIA Formula One World Championship) is the highest class of single-seat auto racing that is sanctioned by the Fédération Internationale de l'Automobile (FIA). The FIA Formula One World Championship has been the premier form of racing since the inaugural season in 1950, although other Formula One races were regularly held until 1983. The "formula", designated in the name, refers to a set of rules, to which all participants' cars must conform. The F1 season consists of a series of races, known as "Grands Prix" (from French, meaning grand prizes), held worldwide on purpose-built F1 circuits and public roads., Michael Schumacher (born 3 January 1969) is a German retired racing driver. He is a seven-time Formula One World Champion and is widely regarded as one of the greatest Formula One drivers of all time. He was named Laureus World Sportsman of the Year twice. He won two titles with Benetton in and before moving to Ferrari where he drove for eleven years. His time with Ferrari yielded five consecutive titles between and ., The McLaren MP4 - 16 was the car with which the McLaren team competed in the 2001 Formula One season . It was driven by double world champion Mika Häkkinen and David Coulthard in what would be their sixth and final season together as McLaren team - mates . After being narrowly pipped to both titles in 2000 by Ferrari , the aim of 2001 was to get McLaren back on top . However , the season proved to be frustrating in more ways than one . The chassis was good , but it was not developed enough to keep pace with Ferrari or new rivals Williams and also suffered from niggling aerodynamic problems ; the Mercedes - Benz engines were less powerful than Williams ' BMW units but less reliable than Ferrari 's in - house efforts ; and the team did not do a good enough job regarding the return of electronic driver aids . Moreover , Häkkinen had his least successful season since 1997 , suffering both from appalling luck and a loss of form at many races . Despite winning two Grands Prix , he elected to retire at the end of the season , and would be replaced by compatriot Kimi Räikkönen . Coulthard , by contrast , produced the best season of his career to date , winning two races early on and mounting a championship challenge to Michael Schumacher . However , McLaren lost this early parity with Ferrari and he was fortunate to keep second place in the Drivers ' Championship ahead of Ferrari 's number two , Rubens Barrichello . Similarly , the team regarded themselves as fortunate to come second in the Constructors ' Championship , with 102 points , ahead of the resurgent Williams team ., Subject: mclaren mp4-16, Relation: sport, Options: (A) auto racing (B) formula one (C) motorsport
