In the initial stages of a multistage amplifier, we use______________?
Correct answer: A. RC coupling
- A. RC coupling
- B. Transformer coupling
- C. Direct coupling
- D. None of the aboveCompare Power Rates
Explanation
RC coupling is commonly used in the voltage-amplifier stages because it is inexpensive and gives good voltage gain with a reasonably flat audio-frequency response. Transformer coupling is more typical at the output stage for impedance matching and power transfer.
