Convolution and LTI systems: A linear system S has the relationship

y[n] = ∑^∞_k=-∞s[k]g[n-2k]

between its input x[n] and its output y[n], where

g[n] = u[n] - u[n-4].

a) Determine y[n] when x[n] = δ[n - 1]

b) Determine y[n] when x[n] = δ[n -2]

c) Is S an LTI system?

Hint: Show the system output with input x[n] = δ[n -1] is y[n] = g[n -2]
