Question

Differentiate between Ring Counter, Johnson Counter, Synchronous, and Asynchronous

Counter.

Answer 1

A straight ring counter, also known as a one-hot counter, links the output of the final shift register to the first shift register input and circles the ring with a single one (or zero) bit. A Johnson counter is a type of ring counter in which the output of the final flip flop is reversed and fed back into the first. It's also referred to as an Inverse Feedback Counter or a Twisted Ring Counter. A synchronous counter is one in which all of the flip flops are timed at the same time using the same clock input. An asynchronous counter, on the other hand, is a device in which all of the flip flops that make up the counter are clocked with separate input signals at various points in time.
