Challenge Problems
Push your limits with challenges.
Question 1
If you have a signal sampled at 5 kHz, what is the maximum frequency of the original signal that can be perfectly reconstructed?
💡 Hint: Use the Nyquist Theorem where the maximum frequency is half of the sampling frequency.
Question 2
Describe the implications of using a sampling frequency below the Nyquist Rate when recording a pulse signal.
💡 Hint: Consider how overlaps in spectral lines may affect the signal's clarity.
