Patent ID: 7932741

Claim:
A device for transmitting signals through a plurality of transmission channels, in a known frequency band, comprising: m signal terminals, a common terminal and a reference terminal, the signal terminals and the common terminal being configured to be connected to an interconnection having at least m+1 conductors, m being an integer greater than or equal to 2; a receiving circuit delivering, when the receiving circuit is in the activated state, p output signals of the receiving circuit corresponding each to a transmission channel, p being an integer greater than or equal to 2 and less than or equal to m, the input of the receiving circuit being coupled to at least p of the signal terminals and to the common terminal, each of the output signals of the receiving circuit being mainly determined by the voltage between one of the signal terminals and the common terminal; and a termination circuit coupled to each of the signal terminals and to the common terminal, the termination circuit being, when the termination circuit is in the activated state, approximately equivalent, for the signal terminals and the common terminal, to a network consisting of m branches, each of the branches having a first terminal and a second terminal, each of the branches consisting of a passive two-terminal circuit element connected in series with a voltage source delivering a constant voltage, the first terminal of each of the branches being connected to one and only one of the signal terminals, the second terminal of each of the branches being connected to the common terminal, each of the signal terminals being connected to the first terminal of one and only one of the branches.
