Step 1
Step 1: The energy of a signal $x(t)$ is given by: $$E_\infty = \int_{-\infty}^{\infty} |x(t)|^2 dt$$ The power of a signal $x(t)$ is given by: $$P_\infty = \lim_{T \to \infty} \frac{1}{2T} \int_{-T}^{T} |x(t)|^2 dt$$ Show more…

1.3. Determine the values of Px and Ex for each of the following signals: (a) x1(t) = e^(-21u(t)) (b) x2(t) = e^(i(21+1T/4) (c) x3(t) = cos(t). In part c, the function is a periodic function. However, when finding the power of the signal, people use the periodic formula. Could anyone explain why?
Adi S.
Find the energy of the following signals. If the energy is infinite, then also find the average power. (b) x2(t) = (1+j)e^-(2+j3)tu(t) (c) x3(t) = 2 sin(4t) cos(4t) (d) x4(t) = 2 sin^2(4t) (e) The following periodic function x5(t) is shown below: x5(t)
Find the normalized power for each signal below that is a power signal and the normalized energy for each signal that is an energy signal. If a signal is neither a power signal nor an energy signal, so designate it. Sketch each signal (α is a positive constant). (a) x1 (t) = 2 cos(4πt + 2π/3) (b) x2 (t) = e-αtu(t) (c) x3 (t) = eαtu(-t) (d) x4 (t) = (a^2 + t^2)^(-1/2) (e) x5 (t) = e-α|t| (f) x6 (t) = e-αtu(t) - e -α(t -1)u(t - 1)
