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 ...

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

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

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.

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.

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 ...

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 ...
