FFT spectrum analyzer based on Matlab NAME : XXXXX Student ID : 00000000000 Professor : 何岭松 Date : 2013-10-08 Abstract Fourier transform is powerful method in signal process. It can transform the signal from time domain to frequency domain. In frequency domain some characteristic is more ...
But the amount of calculation in DFT is large, to speed up in calculation, there isFast Fourier Transform (FFT).For DFT and FFT, as the spectrum is discrete, and only the frequency sampling point is calculated, it caused the fence effect. And the energy leakage for cycle extension. To ...
