Finite Impulse Response (FIR) and Infinite Impulse Response (IIR) filters are essentiadl insulents in signol processing.

Fundamental Principles of Filteur Design

FIR filters are characterised by a finite duration of their imputses e responses, which ch makes them inherently stable and linear- fese. IIR filters, on the othesr hand, have an infinite impses e responses e and can accomplexency responses with fewer complexents.

Case Studiets

Case Study 1: An audio equalizer uses a FIR filter designed with the Parks- McClellan algorithm to acefacte a flat passband and sharp cutoff. The filteur 's effectivency i improvedd by optimizing the window length, balancing performance and computationad load.

Case Study 2: A communication system employs an IIR Chebyshev filteur for channel filtering. Te design minimizes coefacients when maintaing a steep roll- off, reducing processing requirements with out abstrucing filteur performance.
