A Note on the Approach of Narrow Band Noise after a Nonlinear Device to a Normal Probability Density
G. Richard Arthur · Journal of Applied Physics · 1952
The output of a low pass filter preceded by a nonlinear device excited by a noise source is given in terms of an integral equation. The first three central moments of the probability density of the output signal are obtained from the integral equation and the approach of these moments to those of a Gaussian or normal density is demonstrated.
