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. WebY = acosd (X) returns the inverse cosine (cos -1) of the elements of X in degrees. The function accepts both real and complex inputs. For real values of X in the interval [-1, 1], acosd (X) returns values in the interval [0, 180]. For values of X outside the interval [-1, 1] and for complex values of X, acosd (X) returns complex values.
