Problem 3 Three signals r(t), x2(t) and r3(t) are given graphically below (a) Express 2(t), r3(t) in terms of 1(t) using time shifting and amplitude scaling (No time scaling (b) If r1 (t) is applied as input to a linear time invariant system and the corresponding output is y (t) given graphically below as well, determine the outputs of the system y2(t) and y3(t) when r2(t) and 3(t) are applied as inputs respectively.
