Challenge Problems
Push your limits with challenges.
Question 1
Determine the frequency response of a CE amplifier if R1 is changed to 1kΩ and C1 to 100μF. Calculate both cutoff frequencies and the mid-band gain.
💡 Hint: Don't forget to apply the cutoff frequency formulas and the gain calculations.
Question 2
For a CE amplifier intending to amplify audio signals, how would you configure your capacitors R and C to optimize for voice frequencies (300Hz to 3kHz)?
💡 Hint: Focus on filter design principles to manage these frequencies.
