Abstract:
Often the most useful information contained in signals of physiological origin is the period or repetition rate of the waveform. This information is not directly apparent through inspection of the raw signal but must be derived by an additional counting or measuring operation. A review of methods of providing a direct indication of rate, including generating trigger pulses from periodic physiological waveforms and techniques for converting the wave-repetition period into a rate analog are presented. Particular attention is given to the electrocardiographic signals as a vehicle for demonstrating a recommended rate analog processor circuit.
