An Injection Locked Oszillator as Adaptive Filter

Authors: Herbert Weidner

An Injection Locked Synchronous Oscillator is a narrowband digital filter that tracks its frequency to a variable frequency signal. This allows the detection of weak signals of variable frequency despite a strong noise background. The signal is processed in the time domain with negligible phase shift. The calculation effort is much lower than with comparable filter types.
