Challenge Problems
Push your limits with challenges.
Question 1
A continuous signal is sampled at a rate of 1 kHz. What is the sampling period T? If the maximum frequency in the signal is 200 Hz, does this comply with the Nyquist theorem?
💡 Hint: Calculate T using the formula T = 1/fs and compare with the maximum frequency.
Question 2
Discuss how applying an impulse train affects the discrete representation of a continuous signal. Provide an example of a signal and its sampling method.
💡 Hint: Visualize how impulses occur at sample points and how this constructs a digital version of the signal.
