Flip Flop

In S-R flip-flop, if Q = 0 the output is said to be ___________

• a) Set

• b) Reset

• c) Previous state

The flip-flops which has not any invalid states are _____________

• a) S-R, J-K, D

• b) S-R, J-K, T

• c) J-K, D, T

Sequential circuit contains

• a) No memory element

• b) Atleast one memory element

• c) All inputs applied simultaneously

T Flip flop is used as

• Transfer data circuit

• Toggle switch

• Time delay switch

The advantage of a J-K flip-flop over an S-R FF is that ________.

• A.it does not require a clock input

• B.it has only one output

• C.it has no invalid states

Following flip flop is used to eliminate race around problem

• SR Flip flop

• JK Flip flop

• Master Slave Flip flop

Number of inputs for D flip flop

• 3

• 2

• 1

In a J-K flip-flop, if J=K the resulting flip-flop is referred to as

• D flip-flop

• T flip-flop

• S-K flip-flop

The flip-flop is only activated by _____________

• Positive edge trigger

• Negative edge trigger

• Either positive or Negative edge trigger

The logic circuits whose outputs at any instant of time depends only on the present input but also on the past outputs are called

• Combinational Circuits

• Sequential Circuits

• None of the above
