Use the MATLAB or SciPy function ellipap to find the poles, zeros, and gain for a third-order normalized elliptic lowpass filter with 2 dB ripple in the passband and stopband ripple that has an upper limit of -50 dB. Use MATLAB or SciPy to determine the coefficients {bk} and {ak} of the numerator and denominator of the transfer function. Use the transfer function found above to convert the original lowpass filter into the transfer function of a bandstop filter with edge frequencies ωL = 2πfL, where fL = 200 Hz, and ωH = 2πfH, where fH = 2000 Hz. Plot the frequency response on Bode plots using the MATLAB or SciPy function freqs. Use MATLAB or python to plot the magnitude response |H(f)| and the phase response ̸ H(f) of the bandstop filter on Bode plots for 0 Hz ≤ f ≤ 4000 Hz
