Question 1 of 27070

Which class of amplifier has an operating angle of more than 180 degrees but less than 360 degrees when driven by a sine wave signal?

🔍 Key Concepts

• Amplifier conduction (operating) angle definition for each class (A, B, C, AB) • How a sine wave cycle relates to 360 degrees and what "more than 180 but less than 360" physically means • Trade-offs between linearity and efficiency in amplifier classes

💭 Think About

• For each class (A, B, C, AB), think about what portion of the input sine wave the active device conducts current over in one cycle • Which class conducts for the full 360 degrees? Which conducts for exactly 180 degrees or less than 180? The remaining option must match "more than 180 but less than 360" • Consider which class is used as a compromise between the high linearity of Class A and the higher efficiency of Class B and C

✅ Before You Answer

• Be clear on the exact conduction angle ranges for A, B, C, and AB before choosing • Confirm which class is known as a compromise between Class A and Class B operation • Double-check that your choice matches "more than 180 degrees but less than 360 degrees", not exactly 180 or the full 360
