Challenge Problems
Push your limits with challenges.
Question 1
Suppose you have a signal with frequency components of 1500 Hz and 3000 Hz. If the sampling rate is set to 4000 Hz, will aliasing occur? Explain your reasoning.
💡 Hint: Use the Nyquist theorem to evaluate the sampling rate.
Question 2
Design an anti-aliasing filter for a signal with a maximum frequency of 2500 Hz that is to be sampled at 6000 Hz. Specify the cutoff frequency and justify your choice.
💡 Hint: Think about the role of the Nyquist frequency in setting the filter's cutoff.
