The counter on the cutting machine is the simplest basic operation. The counter is the logic circuit that realizes this operation. The counter mainly counts the number of pulses in the digital system to realize the functions of measurement, counting and control. There is a crossover function.
The counter is composed of a basic counting unit and some control gates. The counting unit is composed of a series of triggers with functions of storing information. These triggers include RS trigger, T flip-flop, D flip-flop and JK flip-flop. Wait.
Counters are widely used in digital systems. For example, in the controller of an electronic computer, the instruction address is counted in order to sequentially fetch the next instruction. When multiplying and dividing in the arithmetic unit, the number of addition and subtraction is recorded, and the number is subtracted. Counting pulses in the instrument, etc.
The counter can be used to display the working status of the product. Generally speaking, it is mainly used to indicate how many copies of the product have been completed. Its main indicator is the number of bits in the counter, which is usually 3 and 4 bits. Obviously, the 3-digit counter can be displayed up to 999, and the 4-digit maximum can be displayed to 9999.
