Question 1 of 27070

The class C amplifier output is present for what portion of the input cycle?

🔍 Key Concepts

• Relationship between Class A, B, AB, and C amplifiers and their conduction angle • How conduction angle in degrees relates to distortion and efficiency in RF amplifiers • Meaning of one full input signal cycle (360°) and what fraction each class conducts

💭 Think About

• Recall the typical conduction angle for a Class A amplifier and compare how Class B and Class C differ in terms of how long the active device conducts. • Think about which amplifier class is used for high-efficiency RF power and how this affects how much of the input sine wave it actually conducts. • Match each answer choice to a possible amplifier class’s conduction angle and see which one corresponds to Class C operation.

✅ Before You Answer

• Be clear on what one full cycle = 360° means for the input signal. • Know the usual conduction range for Class A (around 360°) and Class B (around 180°) to bracket where Class C must fall. • Verify that Class C is associated with less conduction time and higher efficiency but more distortion, then match that to the correct degree range.

Question 1 of 27070

The class C amplifier output is present for what portion of the input cycle?

Less than 180 degrees.

Exactly 180 degrees.

360 degrees.

More than 180 but less than 360 degrees.
