The function of this circuit is to read the pulse number and display it in the form of a decimal number using a digital tube, as shown in the figure. Because the highest human pulse rate
is 150 beats/min, a 3-digit decimal counter is sufficient. This circuit uses a dual BCD synchronous decimal counter CC4 518 to form a
3-digit decimal adder, uses a CC4 511 BCD seven-segment decoder to decode, and uses a seven-segment digital tube LTS547R to complete the seven-segment display.
