In differential-mode, ______________?
Correct answer: A. opposite polarity signals are applied to the inputs
- A. opposite polarity signals are applied to the inputs
- B. the gain is one
- C. the outputs are of different amplitudes
- D. only one supply voltage is used
Explanation
Differential-mode operation applies equal signals with opposite polarity to the two inputs, so the amplifier responds to their difference. Equal in-phase signals instead represent common-mode operation.
