Abstract
Infinite Impulse Response (IIR) filter is of recursive type filter. The present output sample of an IIR filter depends on the present input samples, past input samples and past output samples. There are a number of techniques available to determine the digital IIR Filters. This paper is based on the computer based approach to design the digital IIR filter along with the calculation of filter coefficients using the analog to digital mapping technique. The program based on the proposed algorithm is simulated in Matlab and found the result is satisfying.
