The output stage of a multistage amplifier usually employs______________?
Correct answer: A. Push-pull amplifier
- A. Push-pull amplifier
- B. Preamplifier
- C. Class A power amplifier
- D. None of the above
Explanation
The output stage must deliver relatively high power to the load, so it commonly uses a push-pull power amplifier. A preamplifier belongs to an earlier low-level stage, not usually the output stage.
