WebThe frequency spectrum of a typical radio signal from an AM or FM radio transmitter. The horizontal axis is frequency; the vertical axis is signal amplitude or power. It consists of a signal (C) at the carrier wave frequency fC, with the modulation contained in narrow frequency bands called sidebands (SB) just above and below the carrier. WebRadio waves may be propagated in one or more of five modes, depending upon the medium into which they are launched and through which they pass. These modes are: 1. Free space propagation, where radio waves are not influenced by the earth or its atmosphere. 2. Ground wave propagation, where radio waves follow the surface of the earth.
