Try these first

1. 1.

   What is the primary advantage of a Common Emitter amplifier?

   Hint

   Think about the voltage output relative to the input.

2. 2.

   What does a Common Collector amplifier do?

   Hint

   Consider how it affects signal flow.

3. 3.

   What is the main purpose of cascading a Common Collector amplifier?

   • To increase voltage gain
   • To decrease output impedance
   • To reduce input impedance

   Hint

   Consider what happens when you connect stages.

4. 4.

   True or False: A Common Base amplifier is suitable for voltage gain.

   • True
   • False

   Hint

   Think about input resistance characteristics.

5. 5.

   Design a cascading amplifier system featuring a Common Emitter, followed by a Common Collector, and then a Common Base stage. Explain the advantages of each stage in the context of the overall performance.

   Hint

   Consider how each stage influences the next.

6. 6.

   Evaluate a circuit where a Common Base amplifier is in series with a Common Collector. What effects will this have on the gain and bandwidth?

   Hint

   Think about the characteristics of each amplifier type.
