Question
6. What is the state of an RS latch if R is not equal to S and the control input state is equal to zero (0)? 7. It is the state of an RS latch where R S 0 and the control input state is high. 8. It is the state of an RS latch where R is not equal to S, the normal output is high and the control input state is high. 9. It is the state of a JK latch where J K 1 and the control input is high. 10. It is the state of a JK latch where J0, K- 1 and the control input is high. 11. What is the next state of a D-latch if D 1, C 1 and the present state is low? 12. What is the next state of a D-latch if D 0, C 1 and the present state is high? 13. What is the next state of a JK-latch if J = 0, K = 1, C = 1 and the present state is high? 15. What is the state of a latch if the control input is high, the two line inputs have different logic levels but the next state of the normal output is low?Explanation / Answer
6)if control is low then it is hold state means it will show present state.
7)if control =R=S=1 then it is memory state means present state.
8)Output=1 for R=0 and S=1..This is know as set state.
9)When both J=K=1...then it is knows as toggle state and we get inversion of present state.
10)For J=0,K=1 we get output =0 and it is Reset state.
11)For D flip-flop next output is equal =D there for D=1 next state output is 1.
12)For D=0, next state is also zero.
13)For J=0 And K=1 we always get Zero means Reset state .
15)If control is hight and output is low then it is know as Reset state. It occurs when R=1,S=0 or J=0,K=1
