Which of the following is the main limitation of an SR flip-flop?

It has an undefined state when both S=1 and R=1.

It cannot store a bit of data.

It cannot be used in sequential circuits.

It cannot handle asynchronous inputs.

None

what is the correct expression for this logic diagram

AB + (B+C) + BC

AB + (B+C)B+C

AB + BC(B+C)CB

None

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

Multiplexer

D flip-flop

T flip-flop

SR flip-flop

None

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

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.

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.

None

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

The output toggles.

Both outputs become high.

The output remains the same.

The output is undefined.

None

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

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

Synchronous counters have no delay between flip-flops.

Synchronous counters are simpler to design.

Synchronous counters require fewer flip-flops.

None

A 4-bit counter can represent how many unique states?

None

In a down counter, how does the count change with each clock pulse?

The counter does not change with each clock pulse.

The counter jumps between random values.

The counter counts up from 0.

The counter counts down from the maximum value.

None

10.
