Types Of Counter<\/strong><\/h2>\n

The main purpose of the counter is to record the number of occurrence of some input. There are many types of counter both binary and decimal.<\/p>\n

Counter<\/strong><\/h3>\n

The counter is a sequential circuit. A digital circuit which is used for counting pulse is known as a counter. It is the widest application of flip-flops. It is a group of a flip-flop with clock signal applied. Counter are two types.
\n– Asynchronous counter<\/strong>
\n– Synchronous counter<\/strong><\/p>\n

Flip-flips are connected in a such a way that the output of first flip-flop drives the clock of next flip-flop.<\/p>\n<\/td>\n

\n

There is no connection between the output of the first flip-flop and clock of next flip-flop.<\/p>\n<\/td>\n<\/tr>\n

Speed is slow as the clock is propagated though no: of the stage.<\/td>\nSpeed is high as the clock is given at the same time.<\/td>\n<\/tr>\n
