The main advantage of flip-flops over transistor circuit is

(a) immunity from noise

(b) low heating

(c) low propagation delay time

(d) high propagation.

A JK flip-flop has its J input connected to logic level 1 and its K input to the Q

output. A clock pulse is fed to its clock input. The flip-flop will now

(a) change its state at each clock pulse

(b) go to state 1 and stay there

(c) go to state 0 and stay there

(d) retain its previous state

Question>
A rocket has to be launched in d orbit of Jupiter, the dead load of the rocket comprises of 2 draft weights x and y ; to put the rocket in proper path the dead loads have to dropped , only if both of them are dropped at the same instant of time the rocket will attain the proper direction other wise it will put the rocket into spin. Implement the given logic behind this question using as logic gate.

The circuit shown here is called an S-R latch:

write a truth table for the given diagram ( taking set as 0,0,1,1 and reset as 0,1,0,1) in terms of Q' and Q.
