Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is fL defined as?
- The maximum frequency of the amplifier
- The frequency where gain drops to 0.707 of its mid-band value.
- The average voltage output
💡 Hint: Think about where the gain reduction occurs.
Question 2
True or False: The upper cutoff frequency, fH, is primarily determined by external components.
- True
- False
💡 Hint: Focus on internal versus external factors.

Challenge Problems
Push your limits with challenges.
Question 1
Design an amplifier circuit with a desired lower cutoff frequency of 100 Hz. If you choose a coupling capacitor of 10 μF, what will be the required Thévenin resistance?
💡 Hint: Rearrange the formula for R.
Question 2
An amplifier has a fH of 1 MHz. If the internal capacitance is 10 pF, what is the maximum resistance at the input?
💡 Hint: Use the same rearranging method!
