The purpose of RC or transformer coupling is to_____________?
Correct answer: B. Separate bias of one stage from another
- A. Block a.c.
- B. Separate bias of one stage from another
- C. Increase thermal stability
- D. None of the above
Explanation
RC and transformer coupling transfer the AC signal while preventing the DC bias of one stage from disturbing the bias of the next stage. This separation allows each stage to be biased independently.
