1. Signals

Using the discrete-time signals $x_1[n]$ and $x_2[n]$ given below

represent each of the following signals by a graph and by a sequence of numbers

• $y_1[n] = x_1[n] + x_2[n + 1]$
• $y_2[n] = 2x_1[n + 2] + x_2[1 - n]$
• $y_3[n] = x_1[2n] \times x_2[n - 2]$

2. System

Consider an LTI system whose response to the signal $x_1(t)$ is the signal $y_1(t)$ given below
