1.

A discrete time linear shift-invariant system has an impulse response [] with [0] = 1, h[1] = - 1, [2] - 2, and zero otherwise. The system is given an input sequence [] with [0] - [2] - 1, and zero otherwise. The number of nonzero samples in the output sequence [], and the value of [2] are, respectively

Answer» Use convolution to get the result.
