DIGITAL CHEBYSHEV FILTER DESIGN

    The aim of this experiment was to design Digital Chebyshev Filter. This experiment was performed using Scilab. Digital chebyshev filter was designed using BLT method.
    The imput parameters were pass band attenuation(Ap), stop band attenuation(As), pass band frequency(Fp), stop band frequency(Fs) and sampling frequency(F). The observed and theoretical values of Ap and As were compared. More the order of the filter, less will be the difference between observed and theoretical Ap and As values.

    For same specifications, the order of Chebyshev filter is less than that of Butterworth filter, i.e. the number of poles is less in Chebyshev, thus less number of discrete components are required in Chebyshev filter, hence it is preferred

    High order filter gives accurate results but is computationally tedious.

    Chebyshev filter minimize the errors between ideal and actual filter characteristics.

    Chebyshev is characterized by ripples in pass band and monotonic in stop band.

    There is ripple in stop band in Chebyshev 2 filter.
