Relationships Between the Output Autocorrelation Functions of Various Nonlinear Devices Subjected to Signal Plus Noise and Interference

Several zero-memory nonlinear devices whose transfer characteristics are related in some specified manner are considered. This paper discusses the relationships between the output autocorrelation functions of the related devices when they are excited by signal plus Gaussian noise and interference. The results are applied to show how unknown correlation functions can easily be obtained for the exponential device and for power law devices.
