Let xa(t) be a bandlimited signal to max, i.e., Xa(N) = 0,|N| > Nmax. Suppose that the signal is sampled with sampling frequency Fs Z2Fmax (frequencies in Hz). Denote by Ed the energy of x[n] = xa(nTs), i.e., Ed = _- |x[n]|2 and by Ea the energy of xa(t), i.e., Ea = |xa(t)|²dt. Show that Ea Ts Ed = Verify the energy relationship for the bandlimited signal xa (t) with Xa(N) = 2 for 2 € [-1000, 1000TT] and 0 otherwise. Assume that the signal is sampled at the Nyquist rate.
