Challenge Problems
Push your limits with challenges.
Question 1
A signal consists of frequencies ranging from 0 to 3 kHz. You sample this signal at 4 kHz. Describe the hazards of aliasing.
💡 Hint: Apply the Nyquist theorem and consider frequency folding.
Question 2
Consider recording an audio signal which has parts ranging from 10 Hz to 25 kHz. What sampling rate would you recommend, and why?
💡 Hint: Remember the doubling rule of the maximum frequency.
