چکیده
This Paper describes a simple computer-aided design approach for designing Infinite impulse response (IIR) digital filters. IIR filter is essentially a digital filter which depends not only upon the Input data but also upon one or more previous output values. A variety of techniques are available for the designing of IIR Filters. This Paper is based only upon Analog to digital mapping techniques for fast convergence of results. The Simulation Program for digital filter is discussed by an example, LP_1K_0.2K_0.4K_0.2dB_0.4dB, presented in GUI frame and the results are found to be very encouraging. Numerical results are presented to illustrate the performance of proposed method and compared with Matlab filter design toolbox.
