摘要

in the actual situation of measuring an environmental noise, it is very often that only the resultant stochastic fluctuation contaminated b an additional noise of arbitrary dis- tribution type can be observed. In this paper at first a noise cancellation for reasonable removing the effect of the above additional noise, especially in a whole probability distri- bution form, is derived theoretically in order to estimate only the undisturbed objective output response. Next, for the purpose of predicting a whole expression from o the out- put response probability of an acoustic system excited by an arbitrary stochastic input with the additional noise, a new stochastic signal processing method, reflecting the effect of the additional noise fluctuation, is proposed in a whole probability distribution from.
