Ein Injection Locked Oszillator Als Adaptives Filter

Authors: Herbert Weidner

Ein Injection Locked Synchronous Oscillator ist ein schmalbandiges digitales Filter, das seine Frequenz einem frequenzvariablen Signal nachführt. Damit lassen sich schwache Signale veränderlicher Frequenz trotz starkem Rauschhintergrund nachweisen. Das Signal wird im Zeit­bereich bei vernachlässigbarer Phasenverschiebung verarbeitet. Der Berechnungsaufwand ist wesentlich geringer als bei vergleichbaren Filtertypen.
