In parts A and B we design a 9th order Chebvshev filter. However, I'm stuck with part C.
Can you confirm/disprove my method as being correct steps in solving the problem please?
1. Already determined is that we require a 9th order system. So we evaluate the Chebyshev polynomial up to this order.
2. It is required to look at the attenuation within the stop band, so we define the Ls(dB) equation for both filters.
3. As they are in measured in dB we subtract the Ls of the Cheybshev from the Ls of the Butterworth
4. Finally perform the algebraic manipulation for confirm the relationship
I'm at step 4, but can tell its all about to kick off when the Chebyshev polynomials are inserted to the equation.
Thank you in advance
