What is a Decade/Binary Counter?

A Binary Counter is a serial digital counter that counts ten digits. it resets for every new clock input. As it can go through 10 unique combinations of output, it is also called as “Decade counter”. A binary counter can count 0000, 0001, 0010, 1000, 1001, 1010, 1011, 1110, 1111, 0000, and 0001 and so on. A 4 bit binary counter will act as a decade counter by skipping any six outputs out of the 16 (24) outputs.
