Q1. (a) (b) Signal y(t) is given as in Figure 1. Signal y(t) is going through an operation of time shifting and scaling to become signal b(t). If signal b(t) = y(-3). y(t) M -2 -1 Figure 1 (i) sketch signal b(t) (ii) explain the effect on the signal after went through the operations Signal b(t) is the input to the system as shown in Figure 2. Illustrate signal at Point A, Point B and Point C. b(t)- b(t). 23 4 Mixer Mixer A Adder + B Figure 2
