Abstract

In a two-wire line between a transmitter and a receiver, voltage or current pulses are used to transmit information, the content of which is contained in the period duration. This is achieved in that a transmitter connects or disconnects the operating voltage for a receiver using a switch. It is not necessary to have a digital-analog conversion or the reverse. Furthermore, a high pulse-duty factor is used, so that the supplying of the receiver is always guaranteed.
