The Op-amp can amplify______________?
Correct answer: C. both a.c. and d.c. signals
- A. a.c. signals only
- B. d.c. signals only
- C. both a.c. and d.c. signals
- D. neither d.c. nor a.c. signals
Explanation
An op-amp responds to the voltage difference at its inputs regardless of whether the signal is varying or steady, within its operating limits. Therefore it can amplify both AC and DC signals.
