Challenge Problems
Push your limits with advanced challenges
Given a continuous signal with a max frequency of 4 kHz, derive the minimum sampling rate required to avoid aliasing and explain why using the Nyquist theorem is essential.
💡 Hint: Use the relationship defined by the Nyquist theorem.
A signal sampled at 10 kHz contains frequency components of 6 kHz and 8 kHz. Explain what happens when reconstructing this signal.
💡 Hint: Consider the implications of exceeding the Nyquist frequency.
