Q

The chief advantage of Class A audio operation is compared to the other classes of audio-frequency amplifiers:

🔍 Key Concepts

• Class A audio-frequency amplifier biasing and conduction angle • How amplifier classes (A, B, AB, C) trade efficiency vs signal fidelity (distortion) • Effect of operating the active device over the entire input cycle

💭 Think About

• Think about how long the amplifying device (tube or transistor) conducts during the signal cycle in Class A compared to other classes. What does that do to the shape of the output waveform? • Which option directly relates to preserving the original waveform shape in audio applications? Which options instead describe more specialized circuit side‑effects? • In audio service, what is usually the main reason to choose Class A even though it is less efficient than other classes?

✅ Before You Answer

• Identify which choice directly addresses signal quality vs. signal alteration (not circuit convenience or side effects). • Recall that in Class A the device ideally conducts for 360° of the signal cycle—how does that affect distortion? • Verify that the other options describe things that are not unique or primary advantages of Class A operation.
