4. (35 points) An electronics designer has been assigned to design and simulate an analog active low-pass Chebyshev filter for an audio system. The active filter with unity gain must provide a passband ripple of 1.5 dB across a bandwidth of 6 kHz and an attenuation of 28 dB at 8 kHz. (a) Determine the order of this filter. (b) Find poles and obtain the filter transfer function. (c) Plot the pole-zero distribution of the filter in s-plane (Laplace domain) by hand. (d) Propose an electronic circuit topology for this filter using OpAmp. (e) Determine the values for components of the filter
