Answer 1

Answer #1

If the flip flop is SET (Q=1), if S is equal to 0 then it is a active low SR. Latch. Active low SR latch is made using a NAND gate latch.

For a active low SR latch the output is invalid if both inputs are low.

So if Set (S=0) and Reset (R=0) then the output is invalid

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...
