Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What sampling rate must be used to avoid aliasing in a signal with a maximum frequency of 15 kHz?
- 15 kHz
- 30 kHz
- 5 kHz
💡 Hint: Remember, it’s double the highest frequency!
Question 2
True or False: Aliasing can occur if you sample a signal at a rate equal to its Nyquist rate.
- True
- False
💡 Hint: What happens at the Nyquist rate?

Challenge Problems
Push your limits with challenges.
Question 1
If a band-limited signal has frequency components up to 50 Hz and is sampled at 80 Hz, will aliasing occur? Explain your reasoning.
💡 Hint: Use the Nyquist criterion for determining aliasing.
Question 2
A signal has major components at 1 kHz and 3 kHz. If sampled at 4 kHz, assess the potential for aliasing and describe what might happen.
💡 Hint: Evaluate each frequency against the Nyquist rate.
