鎖相環 Phase-Locked Loop 一個鎖相環(PLL)是一個設計用於同步板子時脈與外部的時脈訊號的電路。鎖相環電路會比較外部訊號與電壓控制的石英震盪器(VCXO)之間的相位,接著會去修正震盪器的時脈訊號去與參考訊號的相位之間吻合。因此,訊號之間將會精密的同相。 當在處理訊號擷取時,由於鎖相環會使得多個裝置共享一...
The phase-locked loop (PLL) is one of the key building blocks in many communication systems; providing a means for maintaining timing integrity and clock synchronization. The PLL can be used in various applications such as timing extraction from data streams, jitter mitigation and frequency synthesi...
Since that time, the electronic phase-locked loop principle has been extended to other applications. For example, radio telemetry data from satellites used narrow-band, phase-locked loop receivers to recover low-level signals in the presence of noise. Other applications now include AM and FM demo...
