2. Using functions from MATLAB’s Signal Processing Toolbox, repeat Prob. 2.7-1 for an elliptic filter. Plot the magnitude response to verify specifications are met.

Prob. 2.7-1

Determine the transfer function H(s) and plot the magnitude response H(jω) for a third-order lowpass Butterworth filter if the 3-dB cutoff frequency is ω_c
= 100.
