Practice Questions

Test your understanding with targeted questions

Question 1 Easy

What happens to a signal when it is shifted to the right?

💡 Hint: Think about time and how delaying an event works.

Question 2 Easy

If x(t) is a continuous-time signal, how would you denote advancing it by 1 unit?

💡 Hint: Remember, a negative shift means advancing.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a signal described by x(t) = A sin(ωt). If this signal is delayed by 3 seconds, express the new signal mathematically and interpret its significance.

💡 Hint: Remember how shifting impacts the timing of oscillatory functions.

Challenge 2 Hard

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.

💡 Hint: Think about how you are effectively 'cutting off' the beginnings of the signal.
