Heart rate meter and frequency meter are actually belong to the same class of measuring instruments, but heart rate meter's time the gate is just 1min rather than 1s. For A measuring instrument, 1 min measuring time is not only a long time, but it is difficult to ensure the accuracy of measurement. Therefore it must transform the measurement to match the rapid and accurate requirements. The figure shows a heart rate measuring instrument circuit, and it is consistent with the rapid and accurate requirements.
