Modulation sensorielle — Plusieurs définitions peuvent être attribuées à la modulation sensorielle. En ergothérapie, la modulation sensorielle est un concept clé des théories de l’intégration sensorielle et fait référence à un processus complexe qui permet de réguler et… … Wikipédia en Français
Modulation — For musical change of key, see Modulation (music). For other uses, see Modulation (disambiguation). Passband modulation v · d · e … Wikipedia
Modulation error ratio — The modulation error ratio or MER is a measure used to quantify the performance of a digital radio transmitter or receiver in a communications system using digital modulation (such as QAM). A signal sent by an ideal transmitter or received by a… … Wikipedia
Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… … Wikipedia
Pulse-width modulation — (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load. PrinciplePulse width modulation uses a square wave whose pulse… … Wikipedia
Continuously variable slope delta modulation — (CVSD or CVSDM) is a voice coding method. It is a delta modulation with variable step size (i.e. special case of adaptive delta modulation), first proposed by Greefkes and Riemens in 1970. CVSD encodes at 1 bit per sample, so that audio sampled… … Wikipedia
Quadrature amplitude modulation — (QAM) (Pronounced IPA|kwa:m) is a modulation scheme which conveys data by changing ( modulating ) the amplitude of two carrier waves. These two waves, usually sinusoids, are out of phase with each other by 90° and are thus called quadrature… … Wikipedia
Delta modulation — Principle of the delta PWM. The output signal (blue) is compared with the limits (green). These limits correspond to the reference signal (red), offset by a given value. Every time the output signal reaches one of the limits, the PWM signal… … Wikipedia
Single-sideband modulation — Bande latérale unique Pour les articles homonymes, voir BLU et SSB. La bande latérale unique ou BLU (en anglais : SSB – Single sideband modulation) est un mode de modulation pour la radio qui consiste en une modulation d amplitude dans… … Wikipédia en Français
Video modulation — In Amplitude Modulated (AM) broadcast analogue television systems it is possible to modulate the video signal two ways. Peak White Positive Peak white can be made to correspond to peak transmitter power (100 IRE) and the synchronisation (sync)… … Wikipedia
