Weba) The given periodic signal w (t) is a sum of two sinusoids of different frequencies. The frequency spectrum of w (t) can be obtained using the Fourier transform. The Fourier transform of a sum of sinusoids is a sum of impulses, each located at the corresponding frequency of the sinusoid. Web(b) In Ch. 6, we shall show that a sum of two sinusoids may or may not be periodic, depending on whether the ratio \omega_1 / \omega_2 ω1/ω2 is a rational number. Therefore, the period of this signal is not known. Hence, its power will bedetermined by averaging its energy over T seconds withT → ∞. Thus,
