Abstract
Oppfinnelsen vedrører en fremgangsmåte for automatisk tilpasning av en kodeanordning, særlig en talekodeanordning i et kommunikasjons- sendeapparat, hvor terminalen har minst én mikrofon (MK), hvor mikrofonens (MK) impedans måles og hvor forsterkningen til det via mikrofonen (MK) registrerte talesignal innstilles i avhengighet av mikrofonens (MK) impedans.The invention relates to a method for automatically adapting a coding device, in particular a voice coding device in a communication transmitter, where the terminal has at least one microphone (MK), where the impedance of the microphone (MK) is measured and where the gain of the voice signal recorded via the microphone (MK) is adjusted. depending on the microphone's (MK) impedance.
