Question 1
What is the range that bandwidth covers?
- From fL to fH
- From 0 to maximum gain
- From cutoff to mid-band
💡 Hint: Think about the frequency limits of an amplifier.
Question 2
True or False: The mid-band gain should always be higher than both cutoff frequencies.
- True
- False
💡 Hint: Consider the definitions of gain and frequency.

Challenge Problems
Push your limits with challenges.
Question 1
You measure the input frequency at 500Hz, output voltage at 0.5V for mid-band gain, and notice the output drops to 0.35V at lower and 0.4V at higher frequencies. Calculate the cutoff frequencies and bandwidth.
💡 Hint: Evaluate output voltage as you take frequency readings to determine fL and fH.
Question 2
Consider a multistage amplifier aims for a certain bandwidth of 2000Hz. If fL is at 50Hz, what must be fH?
💡 Hint: Think of the relationship between fL, fH, and BW.
