What are the up and down counters?
What are the up and down counters?
Bidirectional counters, also known as Up/Down counters, are capable of counting in either direction through any given count sequence and they can be reversed at any point within their count sequence by using an additional control input as shown below.
What is the difference between synchronous up and down counter?
We know that for the up and down counters, the design of the circuit is the same. The only difference is that for the up counter the output is taken at the non-inverting output ports of the flip-flops. Whereas, for the down counter, the output is taken at the inverting output ports of the flip-flops.
What is asynchronous up and down counter?
An asynchronous up-down counter includes a plurality of counter blocks. Each of the counter blocks has a counter output, an up-down control output, and an up-down control input. An up-down control signal output from each of the counter blocks has at least two bits.
What is a synchronous up counter?
In synchronous counter, the clock input across all the flip-flops use the same source and create the same clock signal at the same time. So, a counter which is using the same clock signal from the same source at the same time is called Synchronous counter.
What an up down counter also known as?
Explanation: UP-DOWN counter is also known as multimode counter because it has capability of counting upward as well as downwards. Explanation: In DOWN-counter, each flip-flop is triggered by the inverted output of the preceding flip-flop. DOWN-counter counts from a maximum value to 0.
What is synchronous down counter?
What is synchronous and asynchronous counters?
Synchronous counter is the one in which all the flip flops are clocked simultaneously with the similar clock input. On the contrary, an asynchronous counter is a device in which all the flip flops that constitute that counter are clocked with different input signals at different instants of time.
What do you mean by synchronous counter?
synchronous counter A counter consisting of an interconnected series of flip-flops in which all the flip-flop outputs change state at the same instant, normally on application of a pulse at the counter input.
What is a synchronous down counter?
A synchronous counter, in contrast to an asynchronous counter, is one whose output bits change state simultaneously, with no ripple. Asynchronous counter circuit design is based on the fact that each bit toggle happens at the same time that the preceding bit toggles from a “high” to a “low” (from 1 to 0).
