conversion of flip flops

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

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

You are having a D flip-flop, which you want to use as a S-R flip-flop. The input of the D flipflop in terms of external inputs S and R can be written as _______

• D = S + R'Q

• D = R'Q

• D = S

• D = 1

You are having a D flip-flop, which you want to use as a J-K flip-flop. The input of the D flipflop in terms of external inputs J and K can be written as ____

• D = JQ + KQ

• D = J'Q

• D = J'Q + KQ'

• D = KQ'

In the excitation table for a J-K flip-flop, what do we have to apply on the J and K inputs to change the output value from 0 to 1?

• J =K = 1

• J = K = 0

• J = K = D

• J = K = D'
