| Abstract: | FFT is the basis of classical and modern spectrum analysis. Using different win-dew- function, the result of FFT can be obviously different. In this paper, the diagraphic method is used in comparing the influence of Rectangle- window and Hanning - window on the spectrum analysis precision. |

| Keywords: | window-function spectrum FFT |
