By producing pseudorandom number series, we rectify the power spectrums of normal random inputs in the same shape as power spectrums of simulating signals. Through Laplace transformation, we can acquire the frequency response functions of rectifier. Two simulating examples were presented. The power spectrum curves based on one peak function model were almost coincided with the power spectrum curves of simulating loads shown in the figures. Simulating results of input loads had good accuracy. Creating a simulating method and program of input load in this paper was effective.
