A 2-transistor class B power amplifier is commonly called ______________ amplifier?
Correct answer: B. Push-pull
- A. Dual
- B. Push-pull
- C. Symmetrical
- D. Differential
Explanation
In a two-transistor class B stage, the transistors conduct on alternate half-cycles and combine their outputs, forming a push-pull amplifier. This arrangement improves efficiency compared with a single-ended class A stage.
