Chebyshev Filter Design

Chebyshev filter design was done on Scilab software. Chebyshev HPF and LPF required values of stopband and passband attenuation and frequencies along with the sampling frequency. The attenuation and frquency values were taken same as those of Butterworth filter design. The chebyshev filters have ripple in the passband. Also, the order was found to be lesser than that in the Butterworth filter design. This is a major advantage of chebyshev filter design.

  1. Xcos in Scilab can be used for simulation instead of scripting for understanding re-configuring digital filters.

  2. What inputs were given on the Scilab software

  3. Chebyshev 1 has been implemented here.

  4. Even for same input analog filter values for both the filters , the order for Chebyshev filter is less which means its hardware implementation would be easier than Butterworth.

  5. order is less than that of butterworth with same input parameters
