Sequential Circuits Quiz

What is the output of an AND gate when both inputs are 1?

• 0

• 1

• Undefined

• Always 1

Which of the following is the output of an OR gate when both inputs are 0?

• 1

• 0

• Undefined

• 1 only when one input is 1

What is the function of a NOT gate?

• It inverts the input signal.

• It passes the input as output.

• It adds the inputs.

• It compares two inputs.

In a NAND gate, when both inputs are 1, what is the output?

• 0

• 1

• Undefined

• Always 0

Which gate is equivalent to an AND gate followed by a NOT gate?

• OR gate

• NAND gate

• NOR gate

• XOR gate

Which of the following is true for an SR latch?

• It has two inputs: Set (S) and Reset (R).

• The output is determined by the last input received.

• It has no stable state.

• It cannot store data.

What happens when both Set (S) and Reset (R) inputs of an SR latch are 1, assuming the SR latch is built using NOR gates?

• The latch enters an undefined state.

• The latch will reset.

• The latch will set.

• The latch will output 0.

What is the primary difference between a D flip-flop and a T flip-flop?

• The D flip-flop stores the input signal, while the T flip-flop toggles on every clock pulse.

• The D flip-flop toggles the output on every clock pulse, while the T flip-flop stores the input signal.

• The D flip-flop has a clock input, while the T flip-flop does not.

• Both flip-flops operate the same way.

Which of the following is true about a JK flip-flop?

• It has two inputs: J and K.

• When both inputs are 1, the output toggles.

• It can be used to eliminate the undefined state of an SR latch.

• All of the above.

In a T flip-flop, when T = 1, what happens to the output?

• The output stays the same.

• The output toggles.

• The output resets.

• The output is undefined.
