A phase frequency detector compares a reference clock signal to a feedback clock signal to generate pulses in one or more output signals.

相位频率检测器比较基准时钟信号和反馈时钟信号从而在一个或更多个输出信号中生成脉冲。

Then the demodulated signal and the signal of the reference piezoelectric hydrophone were input into a high-resolution digital phase detector to get the phase difference.

然后，解调后的信号和基准压电水听器的信号输入到一个高分辨率的数字鉴相器的相位差。
