phase difference detector

基本解釋

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處理時，設計了一種可精確反映相位差的鑒相器。
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(shù)字電路設計之前，先討論了相位差測量方法，并選定雙向過零鑒相作為實現(xiàn)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.
然后，解調后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(shù)字鑒相器的相位差。
