| Abstract: | In this paper, the off-line autorgressive spectrum analysis system developed on IBM-PC/XT computer is described, and the processing results are siven by using the system. The experiments show that AR spectrum has advantages, such as high resolution and small root mean square deviation compared with FFT spectrum. |
