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. Webduring the period T0. ©2016, B.-P.
