鉴相器

The essential blocks of the synthesizer, the prescaler, the phase detector, the chargepump, and the voltagecontrolled oscillator were presented.

出了合成器的基本模块，包括预频器，鉴相器，充电泵和压控振荡器。

A new type of digital phasometer applied to the infrared laser position-tracking system of mine hoister is introduced in the paper,which is based on FPGA and FFT algorithm.

主要介绍了在矿井升机红外激光位置跟踪系统中种新型数字鉴相器的研究方法,该方法是基于FPGA器件运用FFT算法完成的。
