By which name is non-inverting amplifier quite renowned due to its strategic functionality / mechanism ?

a. Positive Scalar
b. Positive Vector
c. Negative Scalar
d. Negative Vector

Correct Answer : a. Positive Scalar

Explanation :

The necessity of using non-inverting amplifier arises whenever it is essential to obtain an output which should be equal to input with product of positive constant. Hence, it is also renowned by 'Positive Scalar' and this amplifier circuit utilizes negative feedback but along with the provision of desired output in terms of product of input as well as positive constant.
Negative Scaling is especially referred to 'Inverting Amplifier'. Remaining options mentioned above are meant for perplexities & has nothing to deal with non-inverting amplifier.
