摘要：

A straightforward implementation for a phase-locked loop with lock indication is shown. A light emitting diode indicator lights when the loop is locked and goes off when the loop is unlocked. The loop's normal feedback path is opened to accommodate the lock-indicator circuitry. And the free-running frequency of the loop's controlled oscillator must be doubled because of a divide-by-2 network.
