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.
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.
