(b) As an electronics engineer, you are required to design IIR digital low-pass filter to meet the following specifications: Passband frequency Passband peak ripple Stopband frequency Stopband attenuation Sampling frequency 1.2 kHz 0.5 dB 2.5 kHz 50 dB 8 kHz The filter is to be designed by performing a Bilinear transformation method on an analog system function. Thus, i) Compute the filter order, N for Butterworth and Chebyshev Type I (Assume T= 0.5). ii) Compare the difference in the filter order between Butterworth and Chebyshev Type I filter.
