Webb보통 Phase Detector (P/D)라 불리우는 이 비교기는, 두 개의 주파수신호 입력을 받아서 두 개가 얼마나 주파수/위상차가 있는지를 알아내는 놈입니다. 두 개의 주파수 입력신호가 완전히 동일한 주파수만 들어오고 있다면 P/D는 별로 할 일이 없겠죠. WebbA wide range of Analog PLLs is available off-the-shelf. They are also popular for radio front-end applications. Digital phase-locked loops are typically smaller than analog PLLs, due to their digital phase detector and loop filter. However, both analog PLLs and digital PLLs contain analog elements. Thus both PLL types:
