Amplitude Modulation (AM)

Technology / Home Audio / Amplitude Modulation (AM): In radio broadcasting, amethod of modulation in which the amplitude of the carrier voltage is varied in proportion to the changing frequency value of an applied (audio) voltage.

Modulation

Entertainment / Music / Modulation: The process of changing from one key to another. MORE

Intermodulation Distortion

Technology / Home Audio / Intermodulation Distortion: A species of Distortion that results when one set of frequencies is superimposed on, or is modified by, another to produce a third frequency not present in the original signal. Quantifies the distorti MORE

MTF (Modulation Transfer Function)

Entertainment / Photography / MTF (Modulation Transfer Function): A comparison of contrast between a test chart and the reproduced image. One of the measurements of lens performance used in the manufacturing process. MORE

Pulse Width Modulation (PWM)

Technology / Programming / Pulse Width Modulation (PWM): Is a way of simulating an analog output by varying high and low signals at intervals proportional to the value. MORE

Quadrature Amplitude Modulation (QAM)

Technology / Computers / Quadrature Amplitude Modulation (QAM): A method of modulating digital signals using both amplitude and phase coding. Used for downstream and can be used for upstream. MORE

Frequency Modulation (FM)

Technology / Cell Phones / Frequency Modulation (FM): A signaling method that varies the carrier frequency in proportion to the amplitude of the modulating signal. MORE
