6) Consider the RL high-pass filter shown in Figure 5. Find and expression for the complex transfer function H(w). Express this result in terms of the gain G(w) and phase p(w) response of the filter. What is the 3dB response frequency (rad/s). Compare these results with that for the RC high-pass filter; you should find that the RL high pass and the RC high pass have exactly the same functional form.

How did they get c) d) e) f) g)?

First, I'm trying to 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. I think I got this part right.  Then using one of the programs I need to find the coefficients of the numerator and denominator of the transfer function. Then I need to plot the frequency response.  I understand how to use the program for the first part, but I'm unsure how to find the second part. Could you share with me how to approach this?  Thank you for your time and help
