Loop antenna — A shortwave loop antenna A loop antenna is a radio antenna consisting of a loop (or loops) of wire, tubing, or other electrical conductor with its ends connected to a balanced transmission line. Within this physical description there are two very … Wikipedia
Phase-locked loop — PLL redirects here. For other uses, see PLL (disambiguation). A phase locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input reference signal. It is an electronic… … Wikipedia
Delay-locked loop — In electronics, a delay locked loop (DLL) is a digital circuit similar to a phase locked loop (PLL), with the main difference being the absence of an internal voltage controlled oscillator. A DLL can be used to change the phase of a clock signal… … Wikipedia
Ground loop (electricity) — In an electrical system, a ground loop usually refers to a current, generally unwanted, in a conductor connecting two points that are supposed to be at the same potential, often ground, but are actually at different potentials. Ground loops… … Wikipedia
Video signal generator — A video signal generator is a type of signal generator which outputs predetermined video and/or television waveforms, and other signals used to stimulate faults in, or aid in parametric measurements of, television and video systems. There are… … Wikipedia
Bandwidth (signal processing) — Bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a filter, a communication channel, or a signal spectrum, and is typically measured in hertz. In case of a baseband channel or signal, the bandwidth is… … Wikipedia
Delay-locked loop — Une Delay locked loop (DLL) est un dispositif électronique permettant de changer la phase d un signal d horloge. Son fonctionnement est similaire à celui d une Phase Locked Loop, la différence principale étant l absence de VCO dans la DLL. Une… … Wikipédia en Français
Phase Locked Loop (PLL) — A&V A circuit containing an oscillator whose output phase or frequency locks onto and tracks the phase or frequency of a reference input signal. To produce the locked condition, the circuit detects any phase difference between the two signals and … Audio and video glossary
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
