1. A system for the transmission of physiological signals from a patient to a data receiving device comprising;

  • a physiological data acquisition system for the detection of the desired physiological data from the patient and for processing an analog signal corresponding thereto;

    an analog to digital conversion device operatively associated with said acquisition system for converting said analog signals corresponding to said physiological data to a serial digital data stream;

    a spread spectrum signal transmission device which combines said serial digital data stream with a digital code sequence to form a combined transmission signal which is transmitted over a wide frequency bandwidth;

    a spread spectrum signal receiving device which receives said combined transmission signal;

    a data signal demodulation device for separating said serial digital data stream from said digital code sequence;

    a data reformatting processor for the receipt and processing of said serial digital data stream from said demodulation device; and

    a physiological data display, recording and/or analysis device for the receipt of the output from said reformatting processor.
