Given a continuous signal x(t) = sin(t), apply a time scaling factor of 3, and describe the outcome.
💡 Hint: Think about how many cycles occur in a period.
Consider two signals: x1(t) = Acos(ωt) and x2(t) = Asin(ωt). Apply amplitude scaling and then add them. What is the new signal?
💡 Hint: Combining signals can lead to constructs representing waves or more complex shapes.
