Period of a sum of sinusoids
Did you know?
WebThe first three graphs are of sinusoids, whose frequencies are in a 1:2:3 ratio. The common period is marked on the horizontal axis. Each sinusoid has a different amplitude and initial phase. The sum of the three, at bottom, is not a sinusoid, but it still maintains the periodicity shared by the three component sinusoids. 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.
