Question 1
What is the primary purpose of sampling?
- To analyze signals
- To convert continuous signals to discrete
- To eliminate high frequencies
💡 Hint: Think about how digital audio works.
Question 2
True or False: Aliasing can be avoided by sampling at a rate lower than twice the highest frequency.
- True
- False
💡 Hint: Consider the Nyquist theorem.

Challenge Problems
Push your limits with challenges.
Question 1
Given a continuous signal that has frequency components ranging up to 7 kHz, what would be the minimum sampling frequency required to ensure proper sampling according to the Nyquist theorem? Discuss the reconstruction implications if sampling is done at 10 kHz.
💡 Hint: Think about what happens when the sampling frequency falls below the Nyquist rate.
Question 2
If a signal is reconstructed using a non-ideal filter instead of the sinc function, what practical issues might arise during the signal's playback?
💡 Hint: Consider the importance of filter characteristics in reconstruction.
