Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the cutoff frequency of a filter?
- The frequency at which all signals stop
- The frequency where output power is half of input power
- The frequency with the highest signal gain
💡 Hint: Consider when the power output changes significantly.
Question 2
True or False: The Butterworth filter has ripples in its stopband.
💡 Hint: Think about what you need in a smooth transition.

Challenge Problems
Push your limits with challenges.
Question 1
Design a practical Butterworth low-pass filter with a cutoff frequency of 1 kHz using available capacitor values of 0.1 µF and 0.01 µF. Calculate required resistor values.
💡 Hint: Use the cutoff frequency formula, substituting known values.
Question 2
If a second-order Butterworth filter achieves a roll-off of -40 dB/decade, can you explain how this affects the filter's effectiveness at blocking unwanted frequencies?
💡 Hint: Think about how attenuation impacts performance beyond the cutoff frequency.
