Based on the speed of the car body vibration signal analysis
In filtering and adaptive filtering, autocorrelation and cross-correlation, power spectrum and FFT transform, the short-time FFT, cepstrum, resampling, signal processing method of experimental measurement of car body vibration signal and noise signal processing, using a variety of processing methods for comparative analysis of engine speed, for the research and development of vibration speed meter provides a practical signal processing scheme of optimization.
