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'
ReplyDeleteYes.
DeleteTherefore window function is widely used phenomenon

ReplyDeleteRectangular window is rarely used for truncation as As is very low as compared to other window functions.
ReplyDeleteYes.
DeleteAttenuation is stop band is low.
