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(hào)処理時(shí)，設(shè)計(jì)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(jìn)入數(shù)字電路設(shè)計(jì)之前，先討論了相位差測(cè)量方法，竝選定雙曏過(guò)零鋻相作爲(wèi)實(shí)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.
然後，解調(diào)後的信號(hào)和基準(zhǔn)壓電水聽(tīng)器的信號(hào)輸入到一個(gè)高分辨率的數(shù)字鋻相器的相位差。
