41.2.4. Frequency Response from Input to Output

Try these first

1. 1.

   What is a common emitter amplifier?

   Hint

   Think about where the signal enters and exits.

2. 2.

   Define a zero in the context of frequency response.

   Hint

   Consider the opposite effect of a pole.

3. 3.

   What does a pole in the frequency response indicate?

   • Increase in gain
   • Decrease in gain
   • Constant gain

   Hint

   Think of how gain behaves at different frequencies.

4. 4.

   True or False: Zeros contribute to a decrease in gain at their specific frequencies.

   • True
   • False

   Hint

   Recall the role of zeros in frequency response.

5. 5.

   In an amplifier circuit, if C2 is increased from 10µF to 100µF, what changes should we expect in the frequency response? Calculate the new expected gain behavior based on the changes.

   Hint

   Use transfer function adjustments to illustrate changes.

6. 6.

   Given specific numerical values for resistances and capacitances in a CE amplifier, derive the overall frequency response function and determine the location of its poles and zeros.

   Hint

   Ensure all resistance and capacitance interactions are taken into account.
