Time-synchronous-averaging (TSA) is based on the idea of denoising by averaging, and it extracts the periodic components of a quasiperiodic signal and keeps the extracted waveform undistorted. This paper studies the mathematical properties of TSA, where three propositions are given to reveal the ...

Compute and plot the time-synchronous average signal, which corresponds to a period of a sinusoid. Perform the averaging in the frequency domain. Get clf tsa(x,fs,tp,Method="fft")Input Arguments collapse all x— Input signal vector Input signal, specified as a vector. Example: cos(pi/4...
The vibration signal time domain synchronous averaging method comprises the following steps: 1) collecting to get original vibration signals of the variable speed gearbox according to a conventional equal-time-interval way; 2) getting signal frequency signals which are related to the variable speed ...
