Counters are used not only for counting but also for measuring frequency and time ; increment memory addresses . Counters are specially designed synchronous sequential circuits, in which , the state of the counter is equal to the count held in the circuit by the flip flops.
Why are counters important in maths?
In Number Lines, a counter is used to keep track of position on a number line and the act of ‘jumping’ along the line with the counter gives a physical model for addition and subtraction.
How do counters work?
Electronic counters. An electronic counter is a sequential logic circuit which has a clock input signal and a group of output signals that represent an integer “counts” value. Upon each qualified clock edge, the circuit will increment (or decrement, depending on circuit design) the counts.
