Simple Approximation of the Probability Distribution of Peak Values for Broad-band Non-Gaussian Random Signals

摘要

In this paper, we propose a new method for approximating the peak values distribution of non-Gaussian type random signals with a wide frequency band. For peak values dis- tributed above the average level, it is effective to use the approximation method based on level-crossings, which we proposed previously. However, in the case of distributions below the average level, this is not necessarily the best approach. Here, we improve on the well-known peak distribution theory, and propose a simple approximation method which applies non- Gaussian type frequency-band-parameter to the function assuming a Gaussian random pro- Cess.
