一、前言本文介绍一个以Z-80单叛机为基础的数字相关器.它具有结构简单、工作稳定、使用灵活的优点.可对被测信号进行自相关或互相关测试.在输出显示方式上既可以单独显示被测信号的相关函数曲线,也可以动态地显示相关运算的进行过程,便于比较被测信号、参考信号与相关函数在频率上、幅值上和相位上的相互关系.可以从示波器上直接读出栩关波形的频率、幅值及互相关时两波形之间的相位差.一般情况下该相关器工作在伪实时或间歇方式,一次相关处理完后接着进行下一次取样和相关处理.该相关器可
I. INTRODUCTION This paper introduces a digital correlator based on Z-80 single berthing machine, which has the advantages of simple structure, stable work, flexible use, self-correlation or cross-correlation test on measured signal, Can display the correlation function curve of the signal under test independently or dynamically display the operation of the correlation operation to facilitate the comparison of the correlation between the measured signal, the reference signal and the correlation function in frequency, amplitude and phase. From the oscilloscope directly read out the frequency of the waveform, the amplitude and cross-correlation between the two waveforms when the phase difference between the two. Under normal circumstances the correlator work in pseudo-real-time or intermittent mode, a relevant treatment is followed by the next sample And related processing. The correlator can
