ABSTRACT:
For a communication system for the transmission of digital information over a bus channel using pulses having a considerably different pulse length for the transmission of "0" and "1" bits, respectively. In the preferred embodiment the length of a "0" pulse is at least 2.1 times longer than the length of a "1" to pulse, so that the tolerance on detection of the reception has ample room to absorb wide tolerances in the frequency of a RC-clock generator, e.g. .+-.25%, for propagation time delays and for any inaccuracy in the moment of detection when pulse edges of low steepness must be used.
