Abstract

Duplex transmission of digital signals on the single-pair subscriber line is possible if the signals in the two directions are sufficiently separated. An analogue adaptive hybrid is one method of signal separation. We discuss here the theory of analogue adaptive hybrids. We present a model for the system and the adaptive hybrid, and show the result of simulation. The parameters of the adaptive hybrid converge fast to the correct values if no signal is present from the far end.
