window function

In this experiment,we used Hanning window for LPF and HPF filter Design ,by taking Pass band Attenuation (Ap), Stop band Attenuation (As), Pass band Frequency (Fp) in Hz, Stop band Frequency (Fs) in Hz, Sampling Frequency in Hz as an input. we plotted magnitude spectrum and phase spectrum and verified the value of Ap and As in pass band and stop band from the magnitude spectrum.

    The selection criteria of Window functions mainly depends upon the value of attenuation in stop band i.e., 'As'

      Yes.
      Therefore window function is widely used phenomenon

    Rectangular window is rarely used for truncation as As is very low as compared to other window functions.
