Question 1
What is the Nyquist Theorem?
- It states that a signal can be sampled once.
- It states that you need to sample at least twice the highest frequency.
- It states that sampling rate does not affect signal quality.
💡 Hint: Consider the relationship between frequency and sampling.
Question 2
True or False: Oversampling always improves the quality of a digital signal.
- True
- False
💡 Hint: Think about the trade-offs in data processing.
