41.3.1. Example Calculations

Try these first

1. 1.

   What does capacitance do in amplifier circuits?

   Hint

   Think about the signal types.

2. 2.

   Define a transfer function.

   Hint

   Relate it to circuit performance.

3. 3.

   What is a transfer function?

   • A graphical representation of frequency response
   • A ratio of output to input in frequency domain
   • A term for impedance

   Hint

   Think about what describes the circuit output.

4. 4.

   True or False: Poles determine the stability of an amplifier circuit.

   • True
   • False

   Hint

   Recall what affects circuit behavior.

5. 5.

   Derive the complete transfer function for a given CE amplifier circuit.

   Hint

   Identify each component's role systematically.

6. 6.

   Given R1 = 10kΩ, R2 = 5kΩ and C = 1µF, analyze how gain changes if C is halved.

   Hint

   Connect gain behavior to pole frequency calculations.
