After designing Butterworth filtwr there was another IIR filter that was to be designed and that was Chebyshev Filter.
The filter was designed by coding in SCILAB. Both Low Pass and High Pass Chebyshev filters were designed and the results were verified by manual calculations. Increasing the sampling frequency increased the accuracy of the results obtained.

Chebyshev filter is not monotonic..there are either ripples in pass band or stop band.
ReplyDeleteYes! Chebyshev-1 has ripple in pass band and chebyshev-2 has ripple in stop band.
DeleteChebyshev filter consists of steep roll off.
ReplyDeleteMinimum order for chebyshev filter can be 2
ReplyDeleteRipples give the order of filter.
ReplyDeletenicely written
ReplyDeleteThank you!
DeleteHigh order filter gives accurate results but is computationally tedious
ReplyDeleteThe two types of Chebyshev FIlter designs have two ripple in pass and stopband respectively
