In this lab experiment,used a particular windowing function based upon the attenuation in stop band.The different types of windowing functions we have learnt in class were Rectangular,Bartlett,Hamming,Hanning, and Blackman.The specifications of As,Ap, stop band frequency, passband frequency and sampling frequency are taken from the user.It is observed that as the order of the filter increases the number of lobes in frequency response increase.The attenuation depends upon the type of window used where the attenuation is maximum for the Blackman window and minimum for rectangular window.

Blackman window is the best since it has the highest attenuation in the stop band
ReplyDeleteWhich window function did you use?
ReplyDeleteHanning window function was used for this experiment.
ReplyDeleteLarge value of As is desired and hence we don't prefer rectangular window function.
ReplyDeleteYou forgot the title.
ReplyDeleteand A window function is required to truncate infinite samples of hd(n).
Thanks Apoorva..!! i will make the changes
