Question 1
What does amplitude scaling do to a signal?
- It changes the frequency
- It alters the amplitude
- It modifies the phase
π‘ Hint: Think about what aspect of the signal is being modified.
Question 2
If A = 0, what is the output signal?
- True
- False
π‘ Hint: Zero multiplied by any number yields zero.

Challenge Problems
Push your limits with challenges.
Question 1
Consider a signal x(t) = 5 * sin(t). What will be the new signal y(t) if we apply an amplitude scaling factor of -0.5?
π‘ Hint: Calculate with sense of multiplication and consider the sign change.
Question 2
A signal x[n] is defined as a list of sampled values: [1, 2, 3, 4]. If an amplitude scaling factor of 2 is applied, what will the new signal be?
π‘ Hint: Multiply each element of the list by the scaling factor.
