Vibration Signal Extraction Based on FFT and Least Square Method

Vibration Signal Extraction Based on FFT and Least Square Method

Fast Fourier Transform (FFT), widely used in spectrum analysis, is a powerful processing vibration signal to obtain the signal amplitude, frequency, and phase. However, the discrepancy between the FFT derived values and the real values could be introduced due to spectral leakage and spectral interfe...
