A counter is a digital device used to keep track of a numerical value. Counters can be used in various applications, including measuring, timing, and logic circuits.
A counter consists of a register and a set of flip-flops. The register holds the current value of the counter, while the flip-flops control the flow of information into and out of the counter.
The flip-flop is a basic logic circuit that can be used to store a single binary digit. A flip-flop has two inputs, a data input and a clock input. The clock input is connected to a source of constant logic 1, which causes the flip-flop to change state whenever a clock pulse is received.
The data input is connected to the output of the previous flip-flop. This means that the flip-flop will only change state if the data input is different from the current state of the flip-flop.
A counter can be designed with different flip-flop configurations. A modulus counter uses flip-flops with a period of 2, while a binary counter uses flip-flops with a period of 1.
Counters are a fundamental building block of digital logic circuits. They are used to perform a wide variety of operations, such as addition, subtraction, comparison, and sequencing
