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.
Claims11
A circuit arrangement, comprising:
- a transmitter;
- a receiver;
- a two-wire line coupled to said transmitter and said receiver;
- said transmitter including means for generating one of voltage pulses and current pulses by one of connecting and disconnecting an operating voltage, said one of the voltage pulses and current pulses used to code information using a preselected pulse-duty factor and to transmit said information to said receiver via said two-wire line;
- said receiver generating the operating voltage from said one of the voltage pulses and current pulses, and decoding information.
