For a signal:

Derive the expression for the total energy if:

,

where T is the time period of the rectangular pulse, and fc is the frequency of the cosine wave.

Plot the energy spectral density of g(t) in the frequency domain. Using the above expression, calculate the value of the total energy if A = 5.0, and T0 = 0.5s.

Is this value same as the peak value of the energy spectral density of g(t) plotted in the frequency domain? If not, what is the relationship between them?
