Challenge Problems
Push your limits with challenges.
Question 1
You have a complex signal consisting of multiple frequency components: 300 Hz, 800 Hz, and 2500 Hz. What would be the minimum sampling rate to accurately capture this signal?
💡 Hint: Apply the Nyquist theorem formula for the highest frequency.
Question 2
If you used a sampling rate of 1000 Hz on a signal containing frequencies up to 900 Hz, what might be a possible outcome?
💡 Hint: Remember the effects of low sampling rates.
