FLIP FLOP QUIZ

In an SR flip-flop, what is the output when S = 1 and R = 0?

• Reset (Q = 0)

• Set (Q = 1)

• Toggle

• Invalid

What is the forbidden (invalid) condition in an SR flip-flop?

• S = 0, R = 1

• S = 1, R = 0

• S = 0, R = 0

• S = 1, R = 1

The main difference between JK and SR flip-flops is that the JK flip-flop:

• Has two outputs

• Toggles when J = K = 1

• Has only one input

• Is asynchronous

A D flip-flop is also known as a:

• Delay flip-flop

• Toggle flip-flop

• Set-reset flip-flop

• Clock divider

Which flip-flop is best suited for data storage?

• T

• D

• JK

• SR

The T flip-flop toggles its output when:

• T = 0

• T = 1

• Clock = 0

• Inputs are equal

The characteristic equation of a D flip-flop is:

• Q(next) = Q

• Q(next) = D

• Q(next) = D'

• Q(next) = D + Q

Which flip-flop has no invalid state?

• SR

• JK

• RS

• None

A T flip-flop can be made from a:

• D flip-flop

• SR flip-flop

• JK flip-flop

• Any of the above

What will be the output of a JK flip-flop when J = 0 and K = 1?

• Set

• Toggle

• Reset

• No change
