What are the two stable states in a latch or flip flop?

• High and Low

• True and False

• Logic 1 and Logic 0

• On and Off

What is the purpose of the excitation table in the design of flip flops and counters?

• To show the result of the next state based on the control input

• To show the minimum inputs required for the particular next state

• To derive the truth table

• To show the output as the inputs

What happens if both S and R inputs are 0 in an SR latch?

• The output Q will remain unchanged

• The output Q will be set to 1

• The output Q will be reset to 0

• The output Q will toggle between 0 and 1

What is the main difference between SR flip flop and JK flip flop?

• JK flip flop can handle the condition S=R=1, but SR flip flop cannot

• JK flip flop has more number of inputs compared to SR flip flop

• JK flip flop can toggle its output, but SR flip flop cannot

• JK flip flop is faster than SR flip flop

What is the solution to avoid race around condition in JK flip flop?

• Decreasing the clock period t

• Increasing the clock period t

• Using edge trigger clock

• Both a) and c)

How many stable states does a JK flip flop have?

• 1

• 2

• 3

• 4

What is the main use of D flip flop?

• To avoid the propagation delay

• To overcome the racing condition

• To store 1 bit of information

• To store multiple bits of information

What is the purpose of asynchronous inputs in flip flops?

• To make the output state unpredictable

• To change the output state in sync with clock inputs

• None of the above

• To change the output state irrespective of clock and input signals

What is the clock input in a T flip-flop used for?

• To set the output Q to 1

• To reset the output Q to 0

• To synchronize the toggling of the output Q

• To store the input value in the output Q

What is the purpose of Registers in digital devices?

• To store multiple bits of information

• To store a single bit of information

• To store negative values

• To store only 0s
