Abstract
Et signal (LOCK_ALARM) for en låsedetektor i en synteti-sator indikerer i en første tilstand at en sløyfe er låst, og i en andre tilstand at sløyfen ikke er låst. Syntetisatoren kan midlertidig deaktiveres ved å slå av driftsspenningen til en spenningsstyrt oscillator ved hjelp av et koplingssignal ,(CNTRL). Alarmkretsen til syntetisatoren ifølge oppfinnelsen omfatter en første detektor (1), hvis tilstand på utgangen endres med en forsinkelse, som reaksjon på endringen av sig-nalet (LOCK.ALARM) til detektoren overført til detektoren, og en andre detektor (2) hvis utgangstilstand endres med en forsinkelse som en reaksjon på endringen av koplingssignalet (CNTRL) som overføres til detektoren, og en anordning (3) som genererer et alarmsignal, hvilken anordning frembringer ut-gangssignalet (SYNTE.ALARM) for alarmkretsen som reaksjon på detektorenes utgangssignaler. Ved å velge passende tidsforsin-kelser for detektoren, er det mulig å oppnå den tilsiktede virkning.
