phase detector

基本解釋

This paper discusses the two channels output inconsistency of phase detector affecting the signal detection.
討論了相位檢波器兩路輸出不一致對信號檢測的影響。
It uses a delay locked loop (DLL) with a proposed quadrature phase detector to greatly reduce the phase error.
這種方法基於一個採用提出的正交相位檢測器的延遲鎖定環(huán)路來大大減小正交相位誤差。
A way of digital phase detector applied to the laser phase distance measurement system is introduced in this paper, which is based on DSPs and FFT algorithm.
本文介紹了應用於激光相位式測距中的一種數字相位計的實現方法，該方法是基於DSP器件運用FFT算法完成的。

For now, though, the project's still in the baby steps phase -- only 12 feet of the detector (the currently operational portion) has been successfully built out -- so the reality-shattering, scientific epiphanies will have to wait.
ENGADGET
"If the sudden frequency change is neglected, then after only eight hours, a complete rotation of the pulsar is lost in our counting, and we can no longer determine at which rotational phase the gamma-ray photons reach the detector aboard Fermi, " Pletsch explained.

鋻相器
Non-linear phase detector introduces difficulties for loop linear analysis.
非線性鋻相器的引入對環(huán)路線性分析造成了睏難。
相敏檢波
Select frequency amplifier is presented in this paper which amplify the signal from integration circuit, then the signal from select frequency amplifier is demodulated by switched phase detector.
本論文提出選頻放大的方法對前級調制後的信號進行放大,然後通過開關式相敏檢波對放大後的信號進行解調。
