Design of FIR filter using Frequency Sampling Method

Frequency Sampling Method:

In this experiment, the various parameters like pass band attenuation, stop band attenuation, pass band frequency, stop band frequency and sampling frequency are passed as input and the order of the filter is calculated. The flow is shown below :

Hd(w)----------------H(k)------------------h(n)

         (By sampling)             (by IDFT)

I obtained the magnitude response of this by the same way I obtained it for FIR filter by Windowing method.
