🔍 Key Concepts

• Conduction angle of an amplifier (how many electrical degrees of the input cycle the device conducts) • Differences between Class A, Class B, Class C, and Class D operation in terms of conduction time • Relationship between efficiency and linearity/distortion for different amplifier classes

💭 Think About

• For each amplifier class (A, B, C, D), think about how long the active device (transistor or tube) conducts current during one full 360° cycle of the input signal. • Recall which class is known for very high linearity but low efficiency, and which class is known for higher efficiency but more distortion, and match that with a 180° conduction angle. • Eliminate the classes that clearly conduct for more than 180° and less than 180°, then see which one is defined by exactly half-cycle conduction.

✅ Before You Answer

• Be clear on the definition: Class A conducts for the entire 360°, Class C conducts for less than 180°. • Remember that Class D is a switching amplifier class and is not defined primarily by a simple conduction angle like the linear classes. • Double-check which class is specifically described as conducting for one half of the input signal cycle (180°) in your study materials.
