When an input signal drives both inputs of an op amp,both inverting and noninverting amplification occur at the same time and the output is the
A) sum of the two amplified signals.
B) product of the two amplified signals.
C) Thevenin's voltage of the two amplified signals.
D) superposition of the two amplified signals.

Question

Quizplus · Accepted Answer

When both inputs of an op amp are driven by input signals, the output will be the superposition of the two amplified signals, which means that the output will be the sum of the two amplified signals. Therefore, the best choice is D.
