摘要
数字存贮示坡器与ＩＢＭ－ＰＣ机联机通讯后，信号波形数据存在计算机磁盘中。本文介绍数字信号处理的方法以及快速付里叶变换程序的设计，从而获得信号的幅频特性以及相应的功率谱，实现了整个联机系统的自动频谱分析功能。
The interconnect communication between digital storage oscilloscope and IBM-PC microcomputer is come true,the wave data of signal has been stored in disk.In this paper,the method of processing digital singal has been discussed,the author has designed the fast Fourier transform software,has gained signal amplitude spectrum and power spectrum,so the interconnect communication system has the function of frequency spectrum analysis.
