Abstract

PURPOSE:Two voltage control oscillators are used which have narrow working ranges and excellent stabilities, and the frequency defference between both the oscillators is set to be equal to an input signal frequency, thereby obtaining the circuit which has a wide lock-in-frequency-range on synchronization and operates stably.
