After studying the material in this chapter, you should be able to:

1. Identify the Q-point location on the dc load line for class A, class B, class AB, and class C amplifiers.
2. Compare and contrast the ac load line and dc load line of a class A amplifier.
3. Explain the concept of amplifier compliance.
4. Calculate the values of dc input power and ac load power for an RC-coupled class A amplifier.
5. Explain why high amplifier efficiency ratings are desirable in power amplifiers.
6. Describe and analyze the operation of the transformer-coupled class A amplifier.
7. Describe and analyze the operation of class B amplifiers.
8. Perform all the calculations necessary to determine the values of source power and load power for a complementary-symmetry amplifier.
9. Define and describe class AB operation.
10. Explain how class AB operation eliminates crossover distortion and thermal runaway.
11. Perform the complete analysis of a class AB amplifier.
12. Calculate the transistor power dissipation requirements for a given class A, class B, or class AB amplifier.
