Frequency Sampling method. Sounds so good on paper. If time can be sampled, why not frequency? But it was so tough. I don't think anyone could do it the designated turn, and we all sort of did it together. Can't argue was really hard to get the Phase response. But eventually, done.
The verification of the output was easy as an FIR filter always has a linear phase response, so all that had to be checked was the phase response. A linear phase response is all the confirmation needed for verification.

Yeah the pracs was really tough...but we learnt a lot about designing algorithms & how to execute it in c ...
ReplyDeleteThen we took the output of the FSM signal derived from c programme & given it as the ip in scilab to get the.spectrum...we used two software to get op
ReplyDeleteIn practice FIR filters are used when we need a linear phase(ie all input frequencies of different magnitude should get dispersed equally in the output as the group delay is constant and independent of frequency(w) )

ReplyDeleteNo of lobes in frequency response increased with increase in order
ReplyDeleteSince phase is linear, output is not distorted.
ReplyDeleteFrequency Sampling method is more better and efficient realization than Windowing Method.
