Hi NG, I am making an artificial signal, composed of a number of sinusoids which reflect "real" detections/data, but I would like to get closer to the real thing by adding some random noise to the signal. Is there a "standard" way of doing this, provided I have access to a random number generator? Any ideas with regard to the actual implementation are also welcome. I was thinking creating a number of sinusoids with random amplitude and phase (values of which I would get as described above), and then simply adding them to the signal. Would that work from a theoretical point of view? Or, I guess I could also simply just add a random number to each sample..? Any inputs on one or the other? Thanks! Best, M.L.
