Abstract
The invention relates to telephone transmission systems in which frequency multiplexing is carried out by digital processes. It consists in substituting to a computation step of an analytical signal a computation step of a much simpler complex signal. The ultimate signal obtained is not compatible with standard multiplexing apparatus, but may nevertheless be transmitted along ordinary channels.
