Challenge Problems
Push your limits with challenges.
Question 1
Calculate the overall gain of two cascaded CE amplifiers with gains of 15 and 3. Assume the loading effect reduces the total gain by 20%.
💡 Hint: Multiply the individual gains first, then apply the reduction.
Question 2
Describe the effects of adding a buffer with high input resistance but significant output capacitance between two CE amplifiers.
💡 Hint: Consider how the capacitive loading interacts with the resistances in the circuit.
