FIR Filter using Frequency Sampling Method

In frequency response of the obtained output signals of Freqeuncy Sampling Method, rippples in the Stop Band obtained are of decreasing amplitudes. Phase plot of HPF and LPF are same if the order of both of them are same. Phase varies linearly with freqeuncy , hence ouput will not be distracted.

  1. Discontinuity is observed in phase plot between lobes and also when the phase spectrum goes out of the range of -pi to pi.

  2. Zero crossing was observed in phase plot wherever lowest peak was observed in magnitude response.
