Q41 Let a real, energy signal x(t) consist of three signal components, a(t), b(t), and c(t), as x(t) = a(t) + b(t) + c(t). Further, let Ex, Eq, Eb, and Ebe energy of x(t), a(t),b(t), and c(t) respectively. (40M) A) Provide an expression for Ex in terms of a(t),b(t), and c(t). B) Identify three sufficient conditions for Ex = Eq+E, + E, that is the energy of x(t) Equals the sum of energies of the signal component. What is the commonly used term for these conditions among a(t),b(t), and c(t)
