Challenge Problems
Push your limits with challenges.
Question 1
A sound wave has a maximum frequency of 15 kHz. What should its minimum sampling rate be to avoid aliasing? Explain the reasoning behind your answer.
💡 Hint: Utilize the concept of the Nyquist theorem in your calculation.
Question 2
Consider a scenario where a digital audio system fails to apply an anti-aliasing filter before sampling. Describe the potential impacts on the audio quality and reconstructability of the signal.
💡 Hint: Reflect on the relationship between filter usage and signal integrity.
