Extracted text: 2.1-2 (a) Find Ex and Ey, the energies of the signals x(t) and y(t) shown in Fig. P2.1-2a. Sketch the signals x(t) +y(t) and x(t) – y(t) and show that the energy of either of these two signals is equal to Ex + Ey. Repeat the procedure for signal pair in Fig. P2.1-2b. (b) Now repeat the procedure for signal pair in Fig. P2.1-2c. Are the energies of the signals x(t) + y(t) and x(1) – y(t) identical in this case?
