Abstract

An apparatus for determining whether an output signal from an injection locked oscillator is synchronized with an injection signal coming from an input oscillator has a distorter and a level detector. The distorter uses the output signal from the injection locked oscillator to generate a distorter output signal which has a difference tone in a predetermined frequency band if the output signal from the injection locked oscillator is not synchronized with the injection signal. The level detector is designed to detect a level of the difference tone. The apparatus determines, on the basis of the level of the difference tone, whether the output signal from the injection locked oscillator is synchronized with the injection signal.
