Challenge Problems
Push your limits with challenges.
Question 1
Given a continuous signal with a maximum frequency of 10 kHz, determine an appropriate sampling rate that avoids aliasing. Explain your reasoning.
💡 Hint: Remember that the sampling rate must be more than twice the maximum frequency.
Question 2
If you observe aliasing in a sampled signal, what steps would you recommend to identify and rectify the issue?
💡 Hint: Think about both sampling rate and filtering strategies.
