Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the relationship between bandwidth and cutoff frequencies?
- BW = fH - fL
- BW = fL / fH
- BW = fH + fL
💡 Hint: Consider how bandwidth is defined in terms of these frequencies.
Question 2
True or False: The mid-band gain is stable and not affected by frequency-dependent components.
- True
- False
💡 Hint: Evaluate the behavior of the amplifier at mid-range.

Challenge Problems
Push your limits with challenges.
Question 1
Design an amplifier circuit with specific cutoff frequencies of 100 Hz and 2 kHz. Determine the necessary component values for coupling capacitors based on a specified input resistance of 10 kOhm.
💡 Hint: Remember the relationship between frequency, resistance, and capacitance.
Question 2
A single-stage amplifier has mid-band gain of 50 and bandwidth from 400 Hz to 10 kHz. Calculate the gain at the upper cutoff frequency and explain its relevance.
💡 Hint: Focus on the significance of gain drop-offs at fH.
