Abstract:
This paper presents computation of the signal’ s amplitude spectrum and phase spectrum the Fourier transform. Taking the sphere signal as an example, it is found that the phase spectrum is clearer than the amplitude one in resuming input signal. It is pointed that the phase is very important in signal analysis, especially in the seismic signal analysis. But the general method of phase computing and display is very difficult for us to interpret, so the computation and display method are improved. And a simple seismic model is used to demonstrate this method is effective.
