What does the bandwidth of an amplifier refer to?
💡 Hint: Consider what limits an amplifier's performance.
True or False: The upper cutoff frequency is where the amplifier's gain is dropped to 0.5 times its mid-band gain.
💡 Hint: Remember how cutoff frequencies are defined.

Challenge Problems
Push your limits with advanced challenges
An amplifier is designed for audio applications, with fL set to 50 Hz and fH to 20 kHz. It's crucial for the design to cover low to high audio ranges. What considerations must you make for both fL and fH in practical implementation?
💡 Hint: Look at how both capacitive effects can be managed in circuit design.
If an amplifier has an R_Th of 500 Ω and a coupling capacitor of 100 μF, what will the fL be? Is this suitable for audio applications?
💡 Hint: Calculate carefully to find if this fL is appropriate for typical audio signals.
