摘要
The Fast Fourier Transform (FFT) is widely used for the analysis of time series data recorded in the course of experimental work where vibration or other time dependent phenomena are under investigation. The paper gives a method of obtaining high frequency resolution of spectral peaks when time series data is transformed to the frequency domain by means of a simple Fast Fourier Transform.
