1. Given x[n] and h[n], find y[n] = x[n] * h[n] (where * is the convolution operation)
a. x[n] = \begin{cases} 1 & n = 0, 1, 2\\ 0 & \text{otherwise} \end{cases}
h[n] = \delta[n - 2]
b. x[n] = \begin{cases} -n & n = -1, 1, 2\\ 0 & \text{otherwise} \end{cases}
h[n] = \begin{cases} 1 & n = 0, 1, 2\\ 0 & \text{otherwise} \end{cases}
