The output power of the cascaded amplifier / attenuator system can be determined using___________?
Correct answer: B. Actual gain of amplifier and attenuator
- A. Actual gain of amplifier
- B. Actual gain of amplifier and attenuator
- C. Gain in dB of amplifier and attenuator
- D. Actual gain of attenuator
Explanation
For cascaded stages, the total actual voltage or power gain is found by multiplying the amplifier gain by the attenuator’s transmission factor, then applying it to the input power. The attenuator factor is less than one, so it reduces the amplifier output.
