Question 1
What does the overall bandwidth of cascaded amplifiers do compared to a single stage?
- Increases
- Decreases
- Stays the same
💡 Hint: Consider the impact of multiple stages.
Question 2
True or False: The overall upper cutoff frequency is determined by the highest upper cutoff frequency of the stages.
- True
- False
💡 Hint: Think about which stage limits the high-frequency response.

Challenge Problems
Push your limits with challenges.
Question 1
Design a multistage amplifier with three different stages where the individual gains are 5, 10, and 15. What is the overall gain, and what will the bandwidth be if the first stage has a lower cutoff of 100 Hz and a high cutoff of 800 kHz?
💡 Hint: Keep in mind how each stage contributes to the total gain and filters the frequency.
Question 2
What would happen if the low cutoff frequencies of all three stages are reduced to 50 Hz? Calculate the new overall lower cutoff frequency and discuss the implications.
💡 Hint: Use the formula for the overall lower cutoff frequency to verify.
