Question 1

What happens to a signal during amplitude scaling with A > 1?

The signal is inverted
The signal is amplified
The signal is compressed

💡 Hint: Think about how tall the signal gets.

Question 2

True or False: Time reversal can make a sound play backward.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a continuous signal x(t), explain how to create a new signal y(t) that is 4 times x(t) and advanced by 1 second.

💡 Hint: Consider the order of operations carefully.

Challenge 2 Hard

Describe what will happen if a signal is time scaled with a factor of 0.25 and then time shifted by 2 units to the right.

💡 Hint: Focus on how each operation affects the signal's characteristics.
