The electronic circuit in turn is connected to a detector circuit for detecting the peak amplitude of each burst of alternating signal and to produce an electrical pulse related in time thereto, the detector circuit in turn being connected to a microcomputer which measures the time between pulses and selectively converts the measured times into a number representing heart beat rate, the microcomputer being in turn connected to a display for displaying the number representing heart beat rate.Field of SearchBIOLOGICAL SIGNAL AMPLIFIER | |
