A digital Chebyshev filter using the analog filter and input specifications was designed.
Scilab software was used to write the code and also observe the output magnitude spectrum with frequency (Hz) on X axis and attenuation (dB) on Y axis.
The conspicuous feature of the magnitude spectrum was that it exhibited ripple in passband and no monotonic in stop band.
The order of Chebyshev filters was observed to be lesser compared to Butterworth filters for similar input parameters.
This means that the Chebyshev filter requires less hardware components for its realization.

Chebyshev filter has ripples in pass band and stop band
ReplyDeleteYes. True
DeleteMinimum order of chebyshev filter is 2
ReplyDeleteorder of chebyshev filter is less than butterworth filter for same input.
ReplyDeletethere is ripple in pass band for chebyshev 1 filter
ReplyDeleteChebyshev2 has ripples in stopband
ReplyDeleteCut off frequency is same as passband frequency
ReplyDeleteOne of the main aspects of the Chebyshev filter is that it has a steep roll-off. It reaches its ultimate roll-off faster than other forms of filter. Accordingly is widely used in RF applications.
ReplyDeleteLowest possible order is 2
ReplyDeleteOkay.
DeleteChebyshev 1 and chebyshev 2 requires less hardware components for realization.
ReplyDeleteChebyshev is characterized by ripples in pass band and monotonic in stop band.
