摘　　要：给出了两同频率正弦信号之间动态相位差的一种测量设计,对测量方法和电路元件都作了比较详细的分析说明,该测量系统不但能显示出两信号相位差的大小,而且还能显示出两信号相位之间的超前或滞后关系。A method for measuring dynamic phase difference between two sine signals with same frequency is given,and putting it into practice by circuit elements is introduced in detail. The measurement system not only displays the value of phase difference,but also display minus while phase lag.
