Challenge Problems
Push your limits with challenges.
Question 1
Consider a CE amplifier with R = 1kΞ© and C = 10Β΅F. Derive the cutoff frequency and plot the Bode plot. What implications do these have for signal processing?
π‘ Hint: Using R and C, derive RC time constants and relate them back to the overall performance.
Question 2
You're given a CS amplifier with a varying load capacitance of 50pF linked to a resistance. How does this load capacitor interact with the existing circuit to influence overall gain?
π‘ Hint: Examine how load impacts gain calculations based on your earlier lessons on capacitive effects.
