A Review on Finite Impulse Response and Infinite Impulse Response Filter Combined Circuit

Abstract

Filters are electronic circuits which used in many applications. Basically filters are circuit of linear type. This is work on the principle of removing the noisy signal, interference in input signal and unwanted distortion from the signal. it is widely used in electronics devices and circuits to improve efficiency related to removing noisy signals and unwanted interference and distortion in noisy signals filters are vital parts of electronics devices various types of filters are found in electronics devices which work on the principle of reducing noise in signals and removed unwanted signals from the channels. In this paper we Review FIR and IIR filters with top level architecture of the combined FIR and IIR filters which used in circuit for remove noise in communication devices and improved efficiency.
