Challenge Problems
Push your limits with challenges.
Question 1
An audio amplifier has a mid-band gain of 15 dB. If the cutoff frequencies are 200 Hz and 4 kHz, determine the bandwidth and discuss its adequacy for high-fidelity sound reproduction.
💡 Hint: Analyze both the values and any practical applications.
Question 2
Explore the impact of increasing the input capacitance on the bandwidth of a BJT amplifier. What might be the implications for amplifier design?
💡 Hint: Consider feedback and design constraints in practical circuits.
