<p>A system for transmitting information along a common channel by means of amplitude division multiplexing. Such a system may be used to transmit RGB video signals to a network of visual display units (VDU). An encoder (1) receives RGB signals and encodes these by amplitude division multiplexing so that the signals can pass along a single channel (3), such as a single coaxial cable. A decoder (4) demultiplexes the received signal and supplies the RGB signals to a VDU or the like. The number of switches in a switching network may thus be greatly reduced and problems associated with different time delays when separate channels are used for the R, G, and B signals are avoided.</p> |
