Challenge Problems
Push your limits with advanced challenges
A signal has frequency components at 60 Hz, 150 Hz, and 300 Hz. What sampling rate would you choose to completely avoid aliasing? Justify your answer.
💡 Hint: Remember to calculate according to the highest frequency present.
Suppose you have sampled audio data and experienced distortion. If you know the maximum frequency present was 22 kHz, what is the minimum sampling rate that would have avoided aliasing?
💡 Hint: Double the maximum frequency to determine the Nyquist rate.
