Up Down Counter in Digital Electronics

A counter which can be made to count in either the forward or reverse direction is called an up-down, a reversible or forward-backward counter. Down Counter A binary counter with a reverse count is called a binary down counter. In Continue reading

Johnson Counter in Digital Electronics

Johnson counter or Switch Tail or Twisted Ring Counter is a synchronous counter. An n-bit ring counter circulates a single bit among the flip flops to provide n distinct states. The number of states can be doubled if the shift register Continue reading

Ring Counter in Digital Electronics

Ring counter is a synchronous counter since all the flip flops are clocked simultaneously. A ring counter is a circular shift register with only one flip flop being set at any particular time, all others are cleared. The single bit Continue reading
