The 26 pages that link to Amplitude modulation, each with the reason it gives.

• Radio broadcastingRelated: AM stations vary carrier amplitude to carry audio over radio waves.

• Frequency modulationCompared with: AM changes carrier amplitude, whereas FM conveys information through frequency changes.

• Radio receiverRelated: Simple envelope detectors can recover audio from many AM broadcasts.

• AmplitudeBroader topic: It uses controlled amplitude changes to carry a message.

• RadioRelated: AM changes the carrier’s strength to carry audio, making it especially vulnerable to static.

• Signal modulationBroader topic: It represents information through the signal property named in this concept’s definition.

• Wireless telegraphyCompared with: Continuous modulation differs from the discrete keyed signals used in classic wireless telegraphy.

• Guglielmo MarconiCompared with: AM broadcasting carried voice and music, unlike Marconi’s early Morse-code telegraphy.

• Analog signalBroader topic: It is a classic radio technique based on analog variation.

• Quadrature amplitude modulationNarrower topic: QAM extends amplitude modulation by controlling two orthogonal carrier components.

• Carrier waveBroader topic: It carries information in changes to the carrier’s amplitude.

• Shortwave radioRelated: Traditional shortwave broadcasting commonly uses amplitude modulation.

• Pulse-width modulationCompared with: It changes signal level rather than pulse width.

• Radio in the United StatesRelated: AM made early voice and music broadcasting practical over long distances.

• Golden Age of RadioRelated: AM transmission carried most early mass-audience radio programs.

• Single-sideband modulationNarrower topic: Single-sideband modulation is a bandwidth-saving form of amplitude modulation.

• Analog televisionRelated: Some television standards encode picture brightness by varying a radio carrier's amplitude.

• Phase modulationCompared with: It varies amplitude, whereas phase modulation keeps amplitude constant.

• Reginald FessendenRelated: Fessenden used amplitude modulation to transmit speech over radio.

• Spark-gap transmitterCompared with: Spark transmitters interrupted wave trains instead of smoothly varying a carrier’s amplitude.

• AM broadcastingRelated: This general technique also appears in communications beyond broadcast radio.

• DemodulationRelated: Its envelope contains the information that simple detectors can recover.

• Crystal radioRelated: The detector recovers audio from the carrier's changing amplitude.

• History of radioBroader topic: AM made continuous speech and music transmission practical for broadcasting.

• History of broadcastingRelated: AM enabled early radio services to carry speech and music over broad areas.

• Kenjiro TakayanagiRelated: Early television experiments transmitted picture information using modulated radio signals.
