Designing FIR & IIR Filter and Comparison Using Matlab

Abstract

Digital filtering is one of the maximum powerful gears of DSP. Digital filters are able to performing that specs which might be extraordinarily difficult to gain with an analog implementation. Similarly the traits of a virtual clear out may be easily changed under software program control. Many virtual structures use sign filtering to get rid of unwanted noise to provide spectral shaping or to perform signal detection or evaluation. Two types of filters provide those capabilities are finite impulse response (FIR) filters and infinite impulse response
(IIR).
