Abstract

See full text

A system for providing X-Y trace coding of multiple parameter recordings through use of a single stylus, single trace recorder by multiplexing multiple signals to the recorder with given time intervals for each multiplexing channel, and in a separate mode by superimposing predetermined waveforms upon the signal information, which superimposed waveforms in coordination with the time the signals are supplied to the recorder and the time of movement of the recorder, moves the stylus to record a given indicia or design, identifying a given channel of information on the single trace recording.
