   Hint

   Think about how we measure amplification.

2. 2.

   Define input resistance.

   Hint

   Consider what happens to the signal at the input.

3. 3.

   What is the primary function of a common collector amplifier?

   • To increase voltage
   • To provide impedance matching
   • To amplify power

   Hint

   Remember its key characteristics.

4. 4.

   True or False: The voltage gain in a common drain amplifier is generally close to 1.

   • True
   • False

   Hint

   Think about its functionality.

5. 5.

   Design a common collector amplifier circuit capable of driving a 8-ohm speaker while maintaining a voltage gain close to one. Explain the calculations involved.

   Hint

   List all components and use Ohm’s law.
