Asynchronous Counter Objective Questions

A 4-bit ripple counter consists of flip-flops, which each have a propagation delay from clock to Q output of 15 ns. For the counter to recycle from 1111 to 0000, it takes a total of

A ripple counter’s speed is limited by the propagation delay of:

What happens to the parallel output word in an asynchronous binary down counter whenever a clock pulse occurs?

A 4-bit counter has a maximum modulus of

A principle regarding most display decoders is that when the correct input is present, the related output will switch

An asynchronous 4-bit binary down counter changes from count 2 to count 3. How many transitional states are required?

One of the major drawbacks to the use of asynchronous counters is that:

A ripple counter’s speed is limited by the propagation delay of:

A 5-bit asynchronous binary counter is made up of five flip-flops, each with a 12 ns propagation delay. The total propagation delay (tp(total)) is

The terminal count of a typical modulus-10 binary counter is

Internal propagation delay of asynchronous counter is removed by

Three cascaded decade counters will divide the input frequency by

How many different states does a 3-bit asynchronous counter have?

How many flip-flops are required to construct a decade counter?

How many natural states will there be in a 4-bit ripple counter?
