Abstract

This paper introduces the advantages of discrete wavelet transform principle and the processing of non-stationary signals. Using TMS320C6713 chip as the core device of the signal processing, a gearbox vibration signal was simulated by wavelet in the environment of CCS, completed the task of wavelet transform. And what is more, we compared its result to another result that has been processed by MATLAB. After three layer wavelet decomposition, not only we got the results of the third layer reconstructed signal, but its envelope spectrum analysis was carried out.
