My problem with this exercise is, that I do not know which number I should plug in the formula and why.

A non-causal moving average system is defined as y[n] = $x[n+ 1] +[n] + 3x[n 1] The input is defined as wmls1, 0 Sns 2 x[n] = lo n 2 Illustrate x[n] and calculate and illustrate y[n] for n=[-2 -1 0 1 2 3 4]
