Please explain how a) is solved, write what formula is used and explain in detail so I can solve any problem of this type. 2) Find the power and energy of the following signals (20 Points). a) x(t) = sin(t) b) y[n] = (-0.3)”u[n – 2] Solutions: Part (a): The signal r(t) is periodic because 1-cos(2t) (t) = sin(t) = ? Therefore, E = 0. To find the power, we can use the fact that the signal is sinusoid: P:...
