Examples

2. In a facsimile transmitter, a device that changes the signal modulation from amplitude modulation (AM) to frequency-shift keying (FSK). Source: Internet

A key consequence of the usual double-sideband amplitude modulation (AM) is that the range of frequencies the signal spans (its spectral bandwidth ) is doubled. Source: Internet

After some amplitude modulation experience with VHF, it was realized that FM radio was a much better alternative for VHF radio than AM. Source: Internet

In particular, all telephone modems faster than 300 bit/s use quadrature amplitude modulation (QAM). Source: Internet

In radio transmission, an advantage of frequency modulation is that it has a larger signal-to-noise ratio and therefore rejects radio frequency interference better than an equal power amplitude modulation (AM) signal. Source: Internet

ITU designations In 1982, the International Telecommunication Union (ITU) designated the types of amplitude modulation: History One of the crude pre-vacuum tube AM transmitters, a Telefunken arc transmitter from 1906. Source: Internet
