What does RS stand for in RS Flip-Flop?
A
Read-Set B
Reset-Set C
Ready-Stop D
Run-Store
Analysis & Theory
`RS` stands for `Reset` and `Set`.
What is the output of RS Flip-Flop when S=1 and R=0?
A
0 B
1 C
No Change D
Invalid
Analysis & Theory
Set input (S=1, R=0) makes output Q=1.
Which condition is invalid in RS Flip-Flop?
A
S=0, R=0 B
S=1, R=0 C
S=0, R=1 D
S=1, R=1
Analysis & Theory
S=1 and R=1 is undefined for RS Flip-Flop.
Which flip-flop toggles its state on T=1?
A
D Flip-Flop B
RS Flip-Flop C
T Flip-Flop D
JK Flip-Flop
Analysis & Theory
T Flip-Flop toggles its output on each clock when T=1.
If T=0 in T Flip-Flop, what happens?
A
Toggle B
Reset C
Set D
No change
Analysis & Theory
T=0 means output remains unchanged.
What does D Flip-Flop do?
A
Sets Q to 0 B
Toggles output C
Stores value of D D
Always sets Q=1
Analysis & Theory
D Flip-Flop stores the value of D input on the clock edge.
Which flip-flop is commonly used to store data bits?
A
T Flip-Flop B
RS Flip-Flop C
D Flip-Flop D
SR Latch
Analysis & Theory
D Flip-Flop is ideal for storing single data bits.
T Flip-Flop can be made from which other flip-flop?
A
RS Flip-Flop B
D Flip-Flop C
Two JK Flip-Flops D
JK Flip-Flop
Analysis & Theory
T Flip-Flop is a JK Flip-Flop with J=K=1.
Which flip-flop has only one input besides clock?
A
RS B
D C
T D
Both D and T
Analysis & Theory
Both D and T Flip-Flops have a single input.
Why is RS Flip-Flop not preferred in modern digital systems?
A
Takes too much power B
Needs two inputs C
Has an invalid state D
Expensive
Analysis & Theory
RS Flip-Flop has an invalid state when S=1 and R=1.
