Try these first

1. 1.

   What is the main advantage of using a Common Emitter amplifier?

   Hint

   Think about the purpose of amplifiers.

2. 2.

   Why is high input resistance beneficial?

   Hint

   Consider how the amplifier interfaces with its source.

3. 3.

   What is the typical voltage gain of a CE amplifier?

   • Less than 1
   • Around 10
   • Greater than 100

   Hint

   Recall the significance of gain in amplifiers.

4. 4.

   Is it beneficial to have low input resistance in a CE amplifier?

   • True
   • False

   Hint

   Think about the effect of resistance on signal flow.

5. 5.

   Given a CE amplifier with specific resistor values, calculate the expected voltage gain and discuss the impact of input capacitance on bandwidth.

   Hint

   Focus on how R affects both voltage gain and overall frequency response.

6. 6.

   Design a CE amplifier circuit that allows for a broad frequency response while ensuring the gain remains above 100.

   Hint

   Consider the balancing act of gain versus frequency effects.
