Which of the following configurations will produce an output that is not phase inverted relative to the input?.
- A.Inverting amplifier
- B.Non‑inverting amplifier
- C.Differential amplifier
- D.Summing amplifier
Model answer
What a good answer should say
- Non‑inverting amplifier
Explanation
Why this works
Formula/rule: A non‑inverting amplifier produces an output that is in phase with the input, unlike an inverting amplifier. Substitution: The output is not phase inverted.
Working: This matches the property of a non‑inverting amplifier. Answer: Non‑inverting amplifier.
Units/conclusion: The circuit is a non‑inverting amplifier.
