DESIGN OF CHEBYSHEV FILTER



This experiment was same as the last execpt in mathematical equations , The  design was implemented for Analog Chebyshev filter using BLT method.Taking Pass band Attenuation (Ap), Stop band Attenuation (As), Pass band Frequency (Fp) in Hz, Stop band Frequency (Fs) in Hz, Sampling Frequency in Hz as an input. magnitude spectrum was plotted and verified the value of Ap and As in pass band and stop band from the spectrum.

    The number of ripples represent the order of the filter.

      right and Poles are inside the unit circle thus filters are stable(HPF and LPF)

    It can be observed that transition band of chebyshev filter is smaller than that of butterworth filter

      yes ,due to its high roll-off the transition band of chebyshev is smaller than butterworth filter
