Question 1
What does the mid-band gain represent?
- It represents the maximum gain of an amplifier in a single frequency.
- It indicates the gain across the entire frequency spectrum.
- It shows the maximum and constant gain within a specified frequency range.
💡 Hint: Think about where in the frequency spectrum you would measure consistent gain.
Question 2
True or False: Coupling capacitors in the mid-band behave as open circuits.
- True
- False
💡 Hint: Think about what happens to AC signals in the presence of a short circuit.

Question 1
Given an amplifier with a gm of 50 mS, a rπ of 1 kΩ, and a ro of 150 kΩ, calculate the mid-band gain.
💡 Hint: Don't forget to handle the parallel resistance calculation correctly.
Question 2
If an amplifier's mid-band gain is 100 but the upper cutoff frequency is reduced, how would this affect audio signal amplification?
💡 Hint: Consider why full frequency response is critical for sound quality.
