The Accomplishment of the Design of FIR Electric Filter Based on MATLAB Program

Comparing handware method,by the way of software,the aim of electric filter can be realized through changing its parameters.Taking wind-function for example,the paper introduces the design idea of FIR electric filter based on MATLAB program suggests the mould and slmulation process of a lowpass filter and discusses the design of belt-pass,high-pass and belt-resist electric filter.Practice proves that this kind of design methed can be used in the design of variovs FIR filter,applied widely in the design of modern electronic system which reguires phase linear channel,and has certain pratical engineering value.
