Given the input x[n] = u[n] and an impulse response h[n] = δ[n] − δ[n−2], compute the output signal y[n].
💡 Hint: Don't forget about the properties of unit step and impulse responses in convolution.
Assume a system's impulse response is h[n] = 0.5^n * u[n]. What is the output for an input x[n] = 2 * u[n] using the convolution sum?
💡 Hint: Remember to think about how the geometric series sums relate to your result.
