In order to obtain diastolic and systolic pressures, it is necessary to match the pulse signal, so the pulse signal is applied as a control signal for the latch to control the display. The moment when the pulse is generated corresponds to the systolic blood pressure, after which the blood pressure gradually decreases, and finally the diastolic blood pressure is displayed.
