鉴相器

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

提出了合成器的基本模块，包括预分频器，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.

主要介绍了在矿井提升机红外激光位置统中种新鉴相器的研究方法,该方法是基于FPGA器件运用FFT算法完成的。
