Abstract

En fremoverkoplings-forsterkningskrets for frembringelse av kompenserte utgangssignaler, omfatter en forsterker innrettet for å motta flere inngangssignaler som innbefatter et styringssignal, innen et forhåndsbestemt frekvensområde, og for å frembringe flere forsterkede signaler som innbefatter styringssignalet, innen det forhåndsbestemte frekvensområdet, hvor det forhåndsbestemte frekvensom- rådet ligger innenfor forsterkerens driftsområde. Faseforskyvningsanordninger er innrettet for å motta inngangssignalene og de forsterkede signalene, og for å inn- føre en relativ faseforskyvning mellom inngangssignalene og de forsterkede signa- lene for å frembringe et feilsignal. Kombineringsanordninger er innrettet for å kombinere feilsignalet med de forsterkede signalene, for å frembringe det kom- penserte utgangssignalet; og styringsanordninger er innrettet for å styre fasefor- skyvningsanordningene i avhengighet av den relative faseforskjell mellom styr- ingssignalet i inngangssignalene og styringssignalet i de forsterkede signalene.
