In an SR latch when Q = 1 and Q' = 0. The latch is in
A. rest state
B. set state
C. initial state
D. reset state
Homework Answers
In an SR latch,
- when the output Q=1, it is said to be in 'SET' state
- when Q=0, it is said to be in 'RESET' state
Hence the answer is B. set state

1- A) The SR latch is different from combinational circuits because it preserves state. That is, unlike combinational circuits, if the inputs change, the circuit keeps its present state. Say that the present state of the SR latch is “set”. We change the values on the two input pins, and the state does not change. What is the value on those input pins? 1- B) Assume that you have a D flip-flop module available to you. Treat it like a...

N1 N2 If R 0 and S 1, it produces a TRUE output on Q. If R-0 and S 0, this circuit will remember the previous value (or state) Q and Qcomplement. If R = 1 and S-1, Both NOR gates produce the FALSE outputs. That is an invalid state If...
