The aim of this experiment was to design a Chebyshev filter using Scilab software.Passband attenuation and frequency (Ap,Fp) and Stopband attenuation and frequency (As,Fs) were given as input parameters to the filter design.The sampling frequency was set greater than 5 times max(Fs,Fp) .The magnitude response of the filter was plotted with frequency in Hz and Magnitude in dB.Ripples were observed in the pass band and the number of extremes in the ripples corresponded to the order of the filter.
Chebyshev Filter requires less hardware.
ReplyDeleteYes agreed..in some applications it requires less parameters.
DeleteThere are ripples in pass band and monotonic in stop band.
ReplyDeleteSo If order is 5 no of ripples is 5 measured from the first peak.
ReplyDeleteHigh order filter gives accurate results but is computationally tedious
ReplyDeleteChebyshev 2 has ripples in stopband.
ReplyDeleteNo of ripples equals order number
