Challenge Problems
Push your limits with challenges.
Question 1
An amplifier has coupling capacitors of 5 µF and 10 µF, and resistor values 1 kΩ and 2 kΩ for input and output, respectively. Calculate both cutoff frequencies and determine the bandwidth.
💡 Hint: Use the cutoff frequency formula for both capacitors individually.
Question 2
Explain the effects of increasing the value of coupling capacitors on lower cutoff frequency and amplifier performance. Discuss with examples.
💡 Hint: Think about the relationship between capacitance value and frequency response.
