Given a non-causal system described by h[n] = δ[n+1] + δ[n]{1}, outline how this system's output would respond to an impulse input.
💡 Hint: Consider the implications of h[n] being non-zero for n < 0.
Design a DT-LTI system characterized by an impulse response that averages its last two inputs. Provide its difference equation.
💡 Hint: The averaging seems to give importance to both current and past inputs.
