Noise analysis of an automatic gain control system
Harry Schachter, Leonard Bergstein · IEEE Transactions on Automatic Control · 1964
A common automatic gain control system is analyzed for a white Gaussian noise input and the effects of the noise on the gain of the system are found. Relations are found between the parameters of the system and the mean and variance of the gain, and the parameters are determined that will reduce the ripple caused by the input noise to a minimum.
