ABSTRACT:
Two signals are generated simultaneously. In order to pass them through a single signal channel, the two signals are time-compressed and rearranged into a time-sequential form by means of pairs of controllable delay lines. The delay lines are controlled from a single drive circuit so that the delay of both is long when clocking is at a low rate. In the long-delay mode, the two delay lines are coupled to the two signal sources to be loaded with signal in parallel. The mode of both delay lines is then switched to a short-delay mode. In order to achieve sequential operation, the mode switching is accompanied by a coupling of the signal output terminal of one of the delay lines to the signal input of the other. In the second mode, the first delay lines clocks out to a system output terminal, while the other clocks to the output terminal through the first, thereby achieving a sequential output signal.
