FIR FILTER DESIGN USING FREQUENCY SAMPLING METHOD

 The objective of this experiment was to design a digital filter for the given input specifications using frequency sampling method. In this method the desired frequency response Hd(w) is sampled at w=2*pi*k/N ( where N = length of  the signal) The frequency samples are thus obtained are taken as DFT coefficients H[k]. FIR filter response is found by taken IDFT of H[k]. Magnitude and phase spectrum were plotted for this. Pass band and stop band attenuation values were verified.

    Frequency sampling method allows us to design FIR filter for
    standard frequency selective filters such as lowpass, highpass, bandpass, etc. and filters with arbitrary frequency response.
