If an op- amp were perfect, the CMRR would

C)approach infinity.
D)be less than one.

Question

Quizplus · Accepted Answer

The Common Mode Rejection Ratio (CMRR) of an operational amplifier (op-amp) measures its ability to reject input signals common to both input terminals. A perfect op-amp would completely reject any common-mode signals, meaning its CMRR would approach infinity, indicating an infinite ability to reject common-mode signals and amplify only the differential signal.
