Web(FM) signals. These notes define the angle modulated signal, of which PM and FM are special cases. FM, under well defined conditions, offers certain features, including a method of trading bandwidth for signal-to-noise ratio. These notes will not discuss signal-to-noise properties, but instead will concentrate on an analysis of the spectral WebThe bandwidth of a time-limited sinusoidal pulse is the transform of the pulse envelope. For a rectangular time window, that transform is a Sinc function. The main lobe of that Sinc is about 2/t in bandwidth, but that contains only a portion of that Sinc's total energy. Since a Sinc has infinite extent, so does the total bandwidth.
