WebFM works just the opposite of AM, (and it’s cousin, Single Sideband). In AM, the frequency is carried by how wide the sidebands are and amplitude is controlled by the volume of the audio, (and is subject to many kinds of interference). In FM, the amplitude is controlled by how far the carrier swings from it’s resting frequency. WebAM ( amplitude modulation) and FM ( frequency modulation) are types of modulation (coding).
