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 advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
