7.2.1. Types of Power Amplifiers

Try these first

1. 1.

   What class of amplifier operates continuously throughout the input signal cycle?

   Hint

   Remember the one known for high fidelity.

2. 2.

   Which amplifier class switches its output transistors on and off rapidly?

   Hint

   Think of efficiency and switching.

3. 3.

   Which amplifier type operates continuously throughout the input signal cycle?

   • Class A
   • Class B
   • Class D

   Hint

   Think of the one known for minimal distortion.

4. 4.

   True or False: Class B amplifiers do not produce any distortion.

   • True
   • False

   Hint

   Consider their switching operation.

5. 5.

   Design a scenario where you would prefer a Class D amplifier over a Class A amplifier. Justify your choice based on efficiency and application needs.

   Hint

   Think about battery-operated devices and the importance of efficiency.

6. 6.

   Explain how Class B amplifiers handle signals differently compared to Class A and what implications this has on audio performance.

   Hint

   Consider the audio quality versus efficiency trade-off.
