Challenge Problems
Push your limits with challenges.
Question 1
A continuous signal has frequency components ranging from 0 to 8 kHz. If you want to avoid aliasing, what should be the minimum sampling frequency?
💡 Hint: Remember Nyquist's theorem: fs must be at least twice the maximum frequency.
Question 2
Describe how you would set up a sampling experiment for an audio signal and explain how you would interpret the results.
💡 Hint: Think about what happens to frequencies when they're not sampled properly.
