Question 1
What is a cutoff frequency?
- The frequency of maximum gain
- The frequency at which gain drops
- The frequency where phase shift occurs
💡 Hint: Reflect on its role in gain modulation.
Question 2
True or False: Lower cutoff frequency indicates the minimum frequency for optimal amplification.
- True
- False
💡 Hint: Think about the implications of amplification limits.

Challenge Problems
Push your limits with challenges.
Question 1
Design a simple common emitter amplifier circuit with given parameters. Calculate the lower and upper cutoff frequencies based on given capacitance and resistance.
💡 Hint: Follow the RC formula!
Question 2
You have an amplifier where lowering the capacitance at the input increases the lower cutoff frequency significantly. Discuss how this affects the amplifier’s ability to amplify low-frequency signals.
💡 Hint: Consider the relationship between capacitance and frequency.
