Question 1

What does amplitude scaling do to a signal?

It changes the frequency
It alters the amplitude
It modifies the phase

💡 Hint: Think about what aspect of the signal is being modified.

Question 2

If A = 0, what is the output signal?

True
False

💡 Hint: Zero multiplied by any number yields zero.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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?

💡 Hint: Calculate with sense of multiplication and consider the sign change.

Challenge 2 Hard

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?

💡 Hint: Multiply each element of the list by the scaling factor.
