This paper describes two graphical methods for the analysis of an automatic control system containing an asymmetrical nonlinear element of zero-memory type for a stationary random input distributed normally with mean zero. The methods are of the following two types. Firstly, we assume that the input to the nonlinear element consists of a stationary random portion and a constant portion. But if the linear part of the control system has a pure integral characteristics, the assumption made above becomes irrational. Nextly, we assume that the input to the nonlinear element consists of two random portions, one with normal distribution and the other with a spectral density around zero frequency. In order to compare the results obtained by the above mentioned two methods, one example is shown.
