Question
Which of the following statements are true related to a Gated R-S latch with an enable input.
Question 4Answer
a. An enable =0 sets the latch Q to 1.
b. An enable =1 prevents the latch from resetting.
c. An enable =0 prevents the latch from changing.
d. An enable =1 allows the latch to change.
Solution
The correct statements related to a Gated R-S latch with an enable input are:
c. An enable =0 prevents the latch from changing.
d. An enable =1 allows the latch to change.
Explanation:
A Gated R-S latch with an enable input works in such a way that when the enable input is 0, no matter what the inputs are, the output will not change, hence the latch is prevented from changing. This is why statement c is true.
When the enable input is 1, the latch is allowed to change according to the inputs of set (S) and reset (R). This is why statement d is true.
Statements a and b are not generally true for a Gated R-S latch with an enable input. The output Q is not necessarily set to 1 when enable = 0, it depends on the previous state and the values of S and R. Similarly, an enable =1 does not prevent the latch from resetting, it allows the latch to change according to the inputs S and R.
