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.

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.

Researchers at the Cavendish Laboratory, University of Cambridge have demonstrated a new way to control radiation in the ...

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, ...

Amplitude modulation occurs when a voice or music signal’s varying voltage (fm) is applied to a carrier frequency (fC). The resultant AM signal consists of the carrier frequency, plus upper and lower ...

The investigation of spin-dependent complex-amplitude modulation and multiplexed interference effects in diatomic all-silicon terahertz metasurfaces is anticipated to have profound implications.
