In this experiment we designed the chebyshev low pass and high pass filter using Scilab. In this experiment, various parameter like pass band attenuation, stop band attenuation, pass band frequency, stop band frequency and sampling frequency are passed as an input and the order of filter is calculated by plotting the magnitude spectrum.
In chebyshev filter there are ripples in pass band but monotonic in stop band. The no. of ripple peaks represent the order of filter. Order of chebyshev filter is always less than that of order of butterworth filter for same input parameters and therefore chebyshev filter requires less hardware components for realisation.

Chebyshev filters are of two types : chebyshev 1 & chebyshev 2
ReplyDeleteYou can also perform it on Matlab
ReplyDeleteYes we can perform on matlab also but I performed on scilab
Deleteno. of ripples is equal to order of filter
ReplyDeleteYes that's one method for getting order of filter
DeleteWhich chebyshev filter was implemented? 1 or 2?
ReplyDeleteChebyshev 1
