ABSTRACT:
Apparatus for multiplexing selected information contained in first and sed pulse waveform signals includes an analog switch through which the first signal passes unchanged except for periods during which the switch is caused to be thrown. The first signal has periods of activity and inactivity. Voltage detectors detect pulses in the second pulse waveform well as periods of activity and inactivity in the first waveform. A logic network is responsive to the voltage detectors and produces a signal triggering a multivibrator to throw the analog switch during a period of inactivity in the first waveform to indicate the occurrence of a pulse in the second pulse waveform.
