Solution

The output of a system is determined by the convolution of the input signal with the system's impulse response. In this case, the impulse response h[n] is given as δ[n]+δ[n-2] and the input x[n] is given as δ[n]-2δ[n-1].

The convolution sum is given by:

y[n] = Σ x[k] * h[n-k]

Substituting the given x[n] and h[n] into the convolution sum, we get:

y[n] = Σ (δ[k]-2δ[k-1]) * (δ[n-k]+δ[n-k-2])

This sum can be simplified by recognizing that the
