Challenge Problems
Push your limits with challenges.
Question 1
Consider a signal described by x(t) = A sin(Οt). If this signal is delayed by 3 seconds, express the new signal mathematically and interpret its significance.
π‘ Hint: Remember how shifting impacts the timing of oscillatory functions.
Question 2
You have a discrete signal x[n] = {1, 2, 3, 4}. What will the new signal be if you advance it by 2 samples? Describe the result.
π‘ Hint: Think about how you are effectively 'cutting off' the beginnings of the signal.
