Concept explainers
A comparator will have a positive output whenever the noninverting input is greater than the inverting input.
Whether the given statement is true or false.
Answer to Problem 1TFQ
The statement is true.
Explanation of Solution
Given:
When the value of the non-inverting terminal is greater than the inverting terminal than the comparator will have a positive output.
The circuit diagram of the op-amp is:
The output is given as:
Now, when the value of the non-inverting input is greater than the inverting input than the output of the comparator op-amp is positive.
Similarly, when the non-inverting terminal is less than the inverting terminal then the output will be negative:
Therefore, the given statement is true that the comparator output will be positive if the value of the non-inverting terminal is greater than the inverting terminal.
