P.10 Consider the signal described by x(t) = { /11 - 1₁/11 <1 0, otherwise. (a) Sketch x(t) and y(t) = -2x(21+1). Is x(t) odd, even, or neither? What about y(t)? (b) Determine the energies of the signals x(t) and y(t). (c) Is there a relation between the energies of x(t) and y(t) = -2x(2t + 1)? If so, show it mathematically. 3
