Abstract:
A method in a transmission system for transmitting signals over a communication channel, the system comprising:a first backward adaptive encoder including a synthesis filter having elements for filter states and also having coefficient elements for predictor coefficients;a second backward adaptive encoder having elements for state values; anda control circuit for switching between said first and second encoders in selecting that one of the encoders which is to be utilized in the transmission;said method comprising:transmitting signals via the second encoder and storing its state values in a buffer;switching, with the aid of the control circuit, for transmission via the first encoder;pre-setting at least a part of the state values of the first encoder with said stored state values;bringing forth at least a part of the predictor coefficients in the first encoder; andgenerating an output signal from the synthesis filter in dependence on the predictor coefficients (A.sub.2 . . . A.sub.51) brought forth.
