Application of Time Frequency Analysis Method in Combustion Audio Signal
摘要
Abstract
The {ire prediction and analysis based on combustion audio are rare. According to the physical characteristics of combustion audio, the combustion audio can be approximated as low frequency impact signal. A new method for combustion audio signal analysis based on continuous wavelet transform (CWT) which is useful in analyzing the spectrum of impact signals is proposed, whose reliability and effectiveness are confirmed by comparing CWT with short time Fourier transform (STFT) and wigner-ville distribution (WVD).关键词
