Question 1
What is the Nyquist frequency?
- Half of the sampling rate
- Equal to the maximum frequency
- Double the highest frequency
💡 Hint: Think about its relationship to sampling.
Question 2
True or False: Sampling at a rate below the Nyquist frequency can lead to signal distortion.
- True
- False
💡 Hint: Remember the effects of insufficient sampling.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a system that samples signals at 30 kHz. Identify the Nyquist frequency and discuss the implications if the signal contains frequencies up to 15 kHz.
💡 Hint: Calculate the Nyquist frequency and assess the original signal's frequency.
Question 2
A telecommunications system is designed to handle frequencies up to 25 kHz. Calculate the minimum sampling rate and discuss the impacts of aliasing if the system only samples at 40 kHz.
💡 Hint: Use the formula for Nyquist sampling and consider what happens with lower rates.
