Q35 / 100
What is the difference between "active high" and "active low" signals?
Correct! Well done.
Incorrect.
The correct answer is A) An active-high signal triggers its associated action when it is at logic 1 (high voltage); an active-low signal triggers its action when it is at logic 0 (low voltage)
A
Correct Answer
An active-high signal triggers its associated action when it is at logic 1 (high voltage); an active-low signal triggers its action when it is at logic 0 (low voltage)
Explanation
The naming convention "active high" or "active low" indicates which logic level (1 or 0) represents the "asserted" or "triggering" state of a signal — often denoted with a bar or "n" suffix for active-low signals.
