WebDec 27, 2024 · Conveniently, there is a sinc() function built into MATLAB. But when you call fft(), if you have enough sample points in your signal, you should actually see the familiar sinc shape in the magnitude of the signal. Be aware that since your time pulse is not centered on the origin, you'll have both real and imaginary parts of your spectrum. You … WebFeb 18, 2024 · The value I've extracted from the matlab-news-group and file-exchange the last 20 odd years by far outweigh what any sensible person would consider paying for my advice, and I would never be cheap or vain enough to peddle them for money, nor do I care too much about the community brownie-points either (as an illustration: John d'Errico was …
WebY = acos(X) returns the Inverse Cosine (cos-1) of the elements of X in radians. The function accepts both real and complex inputs. The function accepts both real and complex inputs. For real values of X in the interval [-1, 1], acos(X) returns values in the interval [0, π]. WebI am trying to implement AM demodulation in Matlab by taking advantage of the fact that in the frequency domain, the spectrum of the modulated signal is shifted by the frequency of the carrier. I wrote code in Matlab that shifts the componenets back and does an inverse Fourier Transform to reconstruct the signal.
