In this experiment we had to design a digital filter using windowing technique and study the spectrum of the filter .We learnt that in the magnitude response of the FIR filter there we ripples present in the stopband of LPF. For BPF and LPF the phase response is linear and the values of Ap and As almost match according to the window used by us.
Window is a good way of filter implementation
ReplyDeleteyes indeed. It smoothens out the signal to give a clean waveform
DeleteWhich window method has less error?
ReplyDeleteBlackman window is the most efficient with least error
DeleteWhat were the input parameters?
ReplyDeletePassband attenuation, Stopband attenuation, Passband frequency, Stopband frequency and Sampling frequency were the input parameters taken
DeleteWhich window was used?
ReplyDeleteBlackman window was used here
Deletewhat is the other method?
ReplyDeletethe other method that could be used is the frequency sampling method
Deletewhich method do you prefer?
