Chebyshev Filter Design

This experiment is performed on scilab. Scilab is one of the two major open-source alternatives for MATLAB.
By giving the input specification we plotted the magnitude plot for High pass and Low pass filter. From the magnitude spectrum it is observed that ripples are present in the pass band. Although it is monotonic is stopband.
In Chebyshev filter the number of ripples represent the order of the filter. 
Chebyshev filter has lower transition period as compared to Butterworth filter. Also, order of the Chebyshev filter is less than order of Butterworth filter. Therefore, less hardware is required for Chebyshev filter.

  2. Chebyshev filters have less order for same input parameters as compared to Butterworth filters. Hence, less computation is required.
    The practical implementation involves use of difference equations.

  3. Chebyshev has low orders and hence it is low cost!
