Question 1.
Define gain in the context of amplifiers.
Show hintHide hint
Think about how effective amplifiers are at increasing signal strength.
Question 2.
What does a pole in amplifier frequency response represent?
Show hintHide hint
It usually marks a transition in the behavior of the amplifier.
3Question 3.
What is the primary function of a bypass capacitor in a CE amplifier?
- Increase gain
- Decrease noise
- Stabilize temperature
Show hintHide hint
Consider the role of capacitors in AC and DC circuits.
4Question 4.
True or False: An increase in the frequency of the input signal results in an infinite gain in an amplifier.
- True
- False
Show hintHide hint
What happens to gain at high frequencies?
Question 5.
Consider a CE amplifier with the following parameters: g = 2 mS, R1 = 10kΩ, R2 = 4kΩ, C = 1μF. Calculate the gain and its frequency response.
Show hintHide hint
Identify your equivalent resistance and substitute values accordingly.
Question 6.
Design a CE amplifier for an audio application requiring a gain of 50. Which parameters would you select to ensure the frequency response suits audio signals?
