Abstract

I en utførelse omfatter en høybånds skurundertrykker en første skurdetektor innrettet for å detektere skurer i et lavbånds talesignal, og en andre skurdetektor er innrettet for å detektere skurer i et tilsvarende høybånds talesignal. Høy- og lavbånds talesignalene kan være forskjellige (eventuelt overlappende) frekvensregioner i et bredbånds talesignal. Høybånds skurundertrykkeren omfatter også en dempesignalkalkulator innrettet for å beregne et dempekontrollsignal i samsvar med en forskjell mellom utganger av den første og den andre skurdetektor. Et forsterkerkontrollelement er innrettet for å anvende dempekontrollsignalet på høybånds talesignalet. i et eksempel indikerer dempekontrollsignalet en dempning når en skur blir funnet i høybånds talesignalet, men er fraværende i et tilsvarende tidsområde i lavbånds talesignalet.
