Challenge Problems

Push your limits with challenges.

Question 1

Given an amplifier circuit operates with a voltage gain of 108 with a coupling capacitor, predict the new gain if the capacitor is removed, and explain why.

💡 Hint: Use the factors discussed in class regarding voltage gain reduction.

Question 2

If an amplifier's input and output impedances are critically tied to its configuration, assess how one would calculate the new output impedance without the presence of capacitors.

💡 Hint: Explore resistances that tend to dominate the path through which signal flows.
