What does amplitude modulation actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well.

Learn how AM and FM modulation work, and how they impact radio waves and modern communication technologies.

There are many different varieties of modulation but they all fall into three basic categories, namely amplitude modulation, frequency modulation and phase modulation, although frequency and phase ...

Measuring Modulation Oct 1, 2004 12:00 PM, By John Battison, P.E., technical editor, RF The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or ...

Digital modulation techniques can also be classified according to the type of signal that is being modulated. Amplitude modulation (AM) is the most common type of digital modulation.

Changing the amplitude by using a voice or music audio signal is amplitude modulation as used for AM radio. Instead, one could modulate a carrier by changing its instantaneous frequency, which is ...

Amplitude modulation (AM) does exactly what its name suggests: the amplitude of an audio signal is modulated by another signal. It's similar to ring modulation, but it contains the original carrier ...

As Soundfly’s Flypaper reports, this is known as amplitude modulation, hence the AM. For FM radio stations, the amplitude remains the same, while the frequency—the number of completed wave ...
