A logic gate is an electronic circuit which
-
Makes logic decisions
-
Allows electron flow only in one direction
-
Works on binary algebra
-
Alternates between 0&1 values
Correct Answer
A. Makes logic decisionsExplanation
A logic gate is an electronic circuit that makes logic decisions by processing input signals and producing output signals based on predefined logical rules. It uses Boolean algebra to determine the output based on the input values. The logic gate analyzes the input signals and determines whether the output should be high or low, representing true or false, on or off, or 1 or 0. Therefore, it can be said that a logic gate makes logic decisions.Rate this question:

In negative logic, the logic state 1 corresponds to
-
Negative logic
-
Zero voltage
-
More negative voltage
-
Lower voltage level
Correct Answer
A. Lower voltage levelExplanation
In negative logic, the logic state 1 corresponds to a lower voltage level. This means that when the logic state is 1, the voltage is lower compared to when the logic state is 0. This is the opposite of positive logic, where the logic state 1 corresponds to a higher voltage level.Rate this question:
