Open the CIPO recordAbstract From the Canadian patent
of the Invention, A device for simultaneously displaying unrelated signals processes the signals separately prior to inputting them to a multiplexer. Under control of a microprocessor the multiplexer switches between the processed signals to alternately pass the signals to the deflection circuits of an X-Y display device at a rate which does not interfere with other frequencies used in the environment where the device is used.
