Challenge Problems
Push your limits with challenges.
Question 1
Given a system that samples an analog signal containing frequencies up to 10 kHz at 12 kHz, assess the accuracy of the sampled wave regarding aliasing.
💡 Hint: Calculate twice the highest frequency.
Question 2
Explain how increasing the number of bits in quantization affects aliasing and overall signal quality.
💡 Hint: Think about the relationship between quantization steps and detail in the sampled signal.
