Modulation in which the amplitude of a carrier wave is varied in accordance with some characteristic of the modulating signal. Note: Amplitude modulation implies the modulation of a coherent carrier wave by mixing it in a nonlinear device with the modulating signal to produce discrete upper and lower sidebands, which are the sum and difference freq [..]

Amplitude Modulation is a type of modulation where the amplitude of the carrier wave is controlled.

A particular technology, most commonly used in radio broadcasting, where blending a modulated signal into a carrier wave by varying the amplitude of the carrier creates the final transmit frequency.

The changing of the amplitude of a radio-frequency or microwave frequency carrier wave. The other method of modulation is called frequency modulation.

TC Amplitude modulation refers to the changing of the amplitude of a radio-frequency or microwave frequency carrier wave. The other method of modulation is called frequency modulation.

A radio broadcast system. AM is acceptable in all references.

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. (Also see Frequency Mo [..]

Used to be the most common type of radio modulation, but has now been overtaken by more sophisticated systems. It works by varying the transmission signal’s amplitude.

(AM). The varying of the amplitude of a signal, usually repetitively. For signals of audible frequency, amplitude modulations in the range of 1 Hz to ~15 Hz evoke a tremolo effect. See also shimmer.

(1) A method of changing a waveform by altering (modulating) its amplitude in response to an input signal. (2) A radio broadcast method that uses amplitude modulation.

Changing the amplitude of a radio wave. A higher wave is interpreted as a 1 and a normal wave is interpreted as a zero. By changing the wave, the RFID tag can communicate a string of binary digits to [..]

The encoding of a carrier wave by variation of it's amplitude in accordance with an input signal. AM Stereo

AM imposes a signal pattern (consistent electrical signal) on a carrier wave by varying the height of a wave, or how far from the center it swings.

A process whereby the amplitude of the carrier is controlled by the modulating signal.

The process in which the amplitude of a carrier wave is varied according to a specific law.
