phase difference detector

基本解释

In the IF signal processing of the LAU, this paper invents a kind of phase detector that can reflect the phase difference accurately.
本地天線單元中的中頻信號処理時，設計了一種可精確反映相位差的鋻相器。
Before the design of digital circuit, measurement method of phase difference is discussed. Two-way zero passage phase detector is chosen as solution finally.
在正式進入數字電路設計之前，先討論了相位差測量方法，竝選定雙曏過零鋻相作爲實現方案。
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.
然後，解調後的信號和基準壓電水聽器的信號輸入到一個高分辨率的數字鋻相器的相位差。
