The aim of the experiment was to design Linear Phase FIR filter using window function. In this experiment we used Hamming window function to design Low pass/high pass fiter. We plotted magnitude as well as phase response.
In this experiment the value of As and Ap are verified. As we go on increasing As depending on the filter the side lobe width decreases & main lobe width increases.

DeleteHamming window has least error
ReplyDeleteThat depends on your application requirements
DeleteFIR implementation is basically trying to perform convolution of the input samples with the stored samples of the sinc (filter taps) function.
ReplyDeleteselection of window based upon application is one of the important thing to do
ReplyDeleteYes that defines the order of your filter
DeleteHamming window has least errors
ReplyDeleteDepends on the application
Deletewhat were the input parameters?
ReplyDeleteThe input parameters are:
Delete1. Stopband attenuation
2. Passband attenuation
3. Stopband frequency
4. Passband frequency
5. Sampling frequency
As it selects the window automatically it is efficient
ReplyDeleteThat is the advantage
DeleteWindow selection is a nice feature. However,the order should be less to reduce number of side lobes.
ReplyDeleteYes
DeleteRectangular Windowing should not be used as it has minimum stop band attenuation.
ReplyDeleteYes, but window selection depends on your application mainly
DeleteVarious window functions are:
ReplyDeleteRectangular
Hamming
Hanning
Blackman
Bartlett
Kaiser
