FM demodulation
In file exchange there is an example of Fmdemodulation but i do not know what beta is; nayone knows something? thank you very much function y = FM(x,beta) [r, c] = size(x); if r*c == 0 y = []; return; end; if (r == 1) x = x(:); len = c; else len = r; end; Df = 2*pi*beta*100; x... 18 Jun 2010 15:43
