Abstract:

A fast design method of IIR digital filter by means of analog filter is presented for the abstract concept and complicated numerical calculation of digital filters.A design system of the IIR filter under the Matlab environment is proposed.The design programs and the run results show that this method offers simpler filter programming and higher design efficiency.

Key words: IIR digital filter;analog filter;Matlab;character of magnitude and frequency
