Design of the filter is essentially application of approximation theory.Computation can be used to make the actual filter properties as near as possible to be desired or given ones so as to eliminate the interference in acquiring signal.This paper,by Z-transform and pole-zero plot,analysed and applied filter frequency characteristics in discrete-tiome system and designed a digital trap with MATLAB.
