Description

The application of signal processing technique to nondestructive evaluation(NDE) has proven successful for years. In particular the time-frequency such as STFT(Short Time Fourier Transform) and WVD(Wigner-Ville Distribution) has been used to enhance the signal detection in presence of background noise. We will investigate the signal detection in AE during the fatigue test. As a result of time-frequency analysis, we can extract the AE from the raw signal and analyze the frequencies in AE signal at the same time.
