For a system that has 1024 unique states, how many flip-flops are necessary to encode the states in binary?

What is the main advantage of a synchronous counter over an asynchronous counter?

Synchronous counters have no delay between flip-flops.

Synchronous counters are faster because all flip-flops are triggered simultaneously.

Synchronous counters require fewer flip-flops.

Synchronous counters are simpler to design.

None

What happens in an SR flip-flop when both inputs S and R are high?

The output is undefined.

The output toggles.

The output remains the same.

Both outputs become high.

None

Which of the following circuits is an example of a combinational circuit?

T flip-flop

D flip-flop

Multiplexer

SR flip-flop

None

Which of the following is a common application of a D flip-flop?

Storing data.

Acting as a counter.

Performing logical OR operations.

Multiplication operations.

None

Assume you are to design a finite state machine to control industrial robot which operates 128 unique states encoded in binary. How many D-flip flops would you need in your design. kindly supply your answer in the space below

simplify x' + xy + xz' +xy'z and supply your answer in the space below

Which of the following is a characteristic of an asynchronous counter?

The output of each flip-flop is synchronized with the clock pulse.

The output of each flip-flop in an asynchronous counter is triggered by the previous flip-flop's output.

The flip-flops in an asynchronous counter are triggered simultaneously by a single clock pulse.

Asynchronous counters require a separate clock pulse for each flip-flop.

None

10.

Which of the following is true for an up-counter?

It can only count to a fixed number.

It operates only in binary.

It counts in an ascending order, from 0 to the maximum count.

It counts in a descending order.

None
