Abstract
In a method for simultaneous transmission of two heterochronous binary signals in the form of a single binary signal on a common physical medium, the second binary signal is timed by a bit clock whose period is greater than the minimal duration allowed for a bit of the first signal. For constituting the single binary signal transmitted there is provision for inserting between transitions of the first binary input signal a brief binary level inverting pulse for each bit of the second input signal which corresponds to the same one of the two possible binary levels of the second signal. Each temporary polarity inversion pulse due to the second signal is placed outside a guard area on either side of transitions of the first signal.
