Question 1
What is the Sampling Theorem used for?
- To convert continuous signals into frequency signals
- To determine the number of samples required for accurate representation
- To eliminate all frequencies in a signal
💡 Hint: Think about why we sample signals.
Question 2
True or False: Aliasing occurs only if the sampling frequency is higher than the Nyquist Rate.
- True
- False
💡 Hint: Consider how frequency components interact during sampling.

Challenge Problems
Push your limits with challenges.
Question 1
A signal has frequency components from 0 Hz to 6 kHz. If you were to sample this signal at 10 kHz, discuss the possible implications.
💡 Hint: Think about the relationship between sampling frequency and maximum frequency.
Question 2
Explain the effect of not using an anti-aliasing filter before sampling a high-frequency signal. Provide a real-world context.
💡 Hint: Consider how filters work to shape frequency responses.
