Pulse-amplitude modulation — Principle of PAM: (1) original signal, (2) PAM signal, (a) amplitude of signal, (b) time Pulse amplitude modulation, acronym PAM, is a form of signal modulation where the message information is encoded in the amplitude of a series of signal… … 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
Pulse-density modulation — Pulse density modulation, or PDM, is a form of modulation used to represent an analog signal in the digital domain. In a PDM signal, specific amplitude values are not encoded into pulses as they would be in PCM. Instead it is the relative density … Wikipedia
Pulse Code Modulation — Die Puls Code Modulation ist ein Verfahren, um ein analoges Signal in ein digitales Signal bzw. Binärcode umzusetzen. Es wird für Audio und Video Signale verwendet. Die Umsetzung erfolgt in folgenden Schritten: Abtastung des analogen Signals… … Deutsch 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
Ultrashort pulse — In optics, an ultrashort pulse of light is an electromagnetic pulse whose time duration is on the order of the femtosecond (10 − 15 second). Such pulses have a broadband optical spectrum, and can be created by mode locked oscillators. They are… … Wikipedia
Femtosecond pulse shaping — In optics, Femtosecond pulse shaping refers to various techniques to modify the temporal profile of an ultrashort pulse from a laser. Pulse shaping can be used to shorten/elongate the duration of optical pulse, or to generate more complex… … Wikipedia
Modulation — For musical change of key, see Modulation (music). For other uses, see Modulation (disambiguation). Passband modulation v · d · e … Wikipedia
Modelocking — Mode locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10 12s) or femtoseconds (10 15s).The basis of the technique is to induce a fixed phase… … Wikipedia
