In this experiment, Low pass and High pass Chebyshev filters were designed. By giving the values of pass band attenuation (Ap), stop band attenuation (As), pass band frequency (Fpass), stop band frequency (Fstop), sampling frequency (Fs) as inputs Low Pass and High pass filters were designed.
As a result order of the filter, cutoff frequency, normalised H(s), denormalised H^(s) and transfer function H(Z) was obtained.
The magnitude response and the pole zero plot was obatined. The filters we designed had ripples in the pass band and was monotonic in stop band indicating it was Chebyshev I filter. Also the ripples obtained verified the order of filter.

Why do we use chebyshev filter?
ReplyDeleteorder is less as compared to butterworth filter.
DeleteHow to distinguish between chebyshev and butterworth?
ReplyDeletebutterworth filter has no ripples in passband
Deleteorder is less than that of butterworth with same input parameters
ReplyDeleteagreed!!
