Question 1
What is the primary role of the cutoff frequency in filter design?
- It determines the filter order
- It sets the transition between passbands and stopbands
- It is irrelevant to filter performance
💡 Hint: Think about where signals start to get reduced.
Question 2
True or False: A higher cutoff frequency always leads to better filter performance.
- True
- False
💡 Hint: Consider the balance of what frequencies are being filtered.

Challenge Problems
Push your limits with challenges.
Question 1
Design a digital filter with a specified cutoff frequency of 500Hz and a filter order of 4. Explain the considerations that lead to your choice of attenuation and the desired phase response.
💡 Hint: Consider how each parameter interacts with others in performance and application.
Question 2
Compare two digital filter designs: one with high attenuation but non-linear phase response, and another with moderate attenuation and linear phase response. Discuss which one would be preferable for audio signal processing.
💡 Hint: Reflect on the specific needs of audio fidelity and quality.
