There have been developed many methods to identify a process. Among them, statistical methods using the correlation function are most popular and practical methods. But these methods have been developed independently. In this paper, it is shown that they can be dealt with systematically when input is white noise. And from the practical point of view, the specified signal named pseudo-random signal is introduced in the analysis. Some consideration about the characteristics of this signal are presented and it is shown that it is applicable for measuring a zeromemory nonlinearity with ease. Measurement data of a distillation column are also presented. From consideration about these data, the obtained results are found to present the average dynamics of the plant.
