The Modification Method of the Matlab Built-in Function PSD Using in the Field of Random Vibration
The process of calculating power spectrum density is introduced. The built fuction PSD in Matlab used in engineering field widely is analyzed in detail. Problems are found when built-in function psd is used to calculated power spectrum density of random signal. Based on such analysis a modification method is proposed.
