The discriminator functin produces an output voltage,this voltage mean direct ratio and two input signals phase diference. 鉴相器的作用是产生一个输出电压,此电压的平均量正比与两输入信号的的相位的差。
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。
