In this experiment, using analog filter parameters like Passband and Stopband Attenuation, Analog Passband and Stopband Frequency as well as sampling frequency we designed digital Chebyshev Low pass and High Pass filter.
We conclude that in Chebyshev filters ,the magnitude spectrum shows ripple in Passband and it is monotonic (no ripple) in Stopband. The advantage is for same analog filter parameters order of Chebyshev filter is less than that of Butterworth filter and thus its realization requires less hardware.

Advantage of Chebyshev filter is explained well.
ReplyDeleteChebyshev filters can be classified into two types, one has ripple in pass band and another in stop band
ReplyDeleteGood content!!
ReplyDeleteThe ripples in passband in case of Chebyshev-1 filters should be avoided as these signals are to be analyzed. Any minor changes in the gain can lead to low performance.
ReplyDeleteThe reduced order,proves to be beneficial in practical applications.
it contains ripples
ReplyDeleteIts order is less than that of butterworth filter
ReplyDeleteChebyshev filters can have minimum order as 2.
