From: kk KKsingh on 22 Jul 2010 23:29 X=fft(X) (so i have frequency from 0:N-1) How can i remove high frequency from the spectrum ! Assuming X is a row vector of 512 samples.. which mean I have 256 negative samples and 256 positive samples.. What should i do to make it band limited to say suppose 20% of samples......How can i remove the columns from x such that both -ve and +ve frequncies can be remove
