D *14.42 Design a low-pass filter to meet the following specifications: fp = 3.4 kHz, Amax = 1 dB, fs = 4kHz, Amin = 35 dB. The dc transmission is unity.
(a) Find the required order of Chebyshev filter. What is the excess (above 35 dB) stopband attenuation obtained?
(b) Find the poles and the transfer function.
