ABSTRACT:
A technique for encoding multiple digital data streams in a limited bandwidth for transmission in a single medium is described. A pulse tuned to an assigned frequency is generated each time a data stream makes a transition. The polarity of each pulse represents the direction of the corresponding transition. In one aspect, a different length pulse is assigned to each incoming data stream to be encoded such that each incoming data stream will generate pulses of different length, thus occupying a different part of the frequency spectrum. These different pulse lengths create a group of "channels" each representing the activities of a different data stream. in each case, the length of the data pulse is shorter than the length of the fastest individual bit to be processed. The pulses are then summed in an analog summer and transmitted as the new, combined data stream.
