Analysis of Time Domain and Frequency Domain of Mechanical Test Signals
Journal Title: Signal and Information Processing - Year 2018, Vol 1, Issue 1
Abstract
Mechanical signal processing is done by transforming some of the measurement signals, weakening the unwanted redundant signals in the mechanical signal, filtering out the mixed noise interference, or turning the signal into a form that is easy to identify in order to extract its eigenvalues. The In this paper, the time-frequency domain processing method of a mechanical signal is introduced. The simulated noisy period signal is constructed by Matlab, and the time-frequency domain is processed. The signal filtering, correlation analysis, power spectrum analysis, and other methods of the characteristics and advantages.
