An emitter follower has ______________input impedance?
Correct answer: C. High
- A. Zero
- B. Low
- C. High
- D. None of the above
Explanation
The input is applied at the base, and the emitter follower's feedback action makes the input resistance high. Its low output resistance is the complementary feature used for buffering.
