Abstract
A method for transmitting two digital signals includes utilizing an encoder to generate a pulse of a fixed width in a coded signal each time a positive going 0-1 transmission is detected in the pulse channel. The polarity of the pulse generated by the encoder is defined by a signal present at the signal channel input. The two digital signals are separated after transmission by a decoder which utilizes the time between two successive level changes. A signal edge in the coded signal initiates a time measurement by the decoder and when a further signal edge appears within a fixed time limit then a signal is allocated to the pulse channel. When, instead, no further signal edge appears within this time limit, the signal is allocated to the signal channel of the decoder.
