FIR filter using windowing method

FIR filter design using windowing method

The aim of the experiment was to design digital filter using windowing method and study the spectrum. The input parameters were passband attenuation(Ap), stopband attenuation(As), passband frequency(Fp), stopband frequency(Fs) and sampling frequency(F). The magnitude and phase spectrum for LPF and BPF using Hanning window were plotted. 

The observed and calculated values of Ap and As were compared. Thus, the values were verified. The phase spectrum was observed to be linear.
