An analog signal uses some property of the medium to convey the signal's information.

" Analog " indicates something that is mathematically represented by a set of continuous values ; for example, the analog clock uses constantly-moving hands on a physical clock face, where moving the hands directly alters the information that clock is providing.

An analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved.

The main difference is that a digital synthesizer uses digital processors and analog synthesizers use analog circuitry.

This version uses the Sega NetLink for online gaming, and has built-in support for the Saturn's analog pad.

Because it uses frequency modulation, SECAM is not linear with respect to the input image ( this is also what protects it against signal distortion ), so electrically mixing two ( synchronized ) SECAM signals does not yield a valid SECAM signal, unlike with analog PAL or NTSC.

In general, modern professional equipment is now all-digital, and uses component-based digital interconnects such as CCIR 601 to eliminate the need for any analog processing prior to the final modulation of the analog signal for broadcast.

A common arrangement uses a series of coils arranged in a helix around the toroid, creating an electrical analog of the mechanical layout.

In contrast to Nortel's DMS-100 which uses individual line cards with a codec, most lines are on two-stage analog space-division concentrators or Line Units, which connect as many as 512 lines, as needed, to the 8 Channel cards that each contain 8 codecs, and to high-level service circuits for ringing and testing.

Since the 1980s, galvanometer-type analog meter movements have been displaced by analog to digital converters ( ADCs ) for some uses.

An analog-to-digital converter ( abbreviated ADC, A / D or A to D ) is a device that uses sampling and quantization to convert a continuous-time and continuous-amplitude signal ( i. e. an analog signal ) to a discrete-time and discrete-amplitude signal ( i. e. a digital signal ).

The underlying technology of transport across DSL facilities uses high-frequency sinusoidal carrier wave modulation, which is an analog signal transmission.

The basic process of digitizing an analog signal is a kind of transform coding that uses sampling in one or more domains as its transform.

A wet bulb thermometer also uses evaporative cooling, so it provides a good analog for use in evaluating comfort level.

Today, a majority of release prints for major studio films still are created with all three digital tracks -- Dolby Digital, DTS and Sony's SDDS ( each digital track uses different film geography so all three, as well as the analog track, can coexist on one print ) -- but most professionals in the industry now consider SDDS a dying system.

Euclid uses the Greek ἀναλόγον ( analogon ), this has the same root as λόγος and is related to the English word " analog ".

The professional CCIR 601 digital video format also uses Y ' CbCr at the common chroma subsampling rate of 4: 2: 2, primarily for compatibility with previous analog video standards.

Subscription-based cable television from Virgin Media uses DVB-C, alongside a limited selection of analog channels.

An analog or analogue synthesizer ( or analog synth ) is a synthesizer that uses analog circuits and analog computer techniques to generate sound electronically.

The initial paper describing the concept listed possible uses as a memory, a delay line, and an imaging device.

Examples of a one-way time transfer system are the clock on a church or town building and the ringing of their time-indication bells ; time balls, radio clock signals such as LORAN, DCF77 and MSF ; and finally the Global Positioning System which uses multiple one-way time transfers from different satellites, with positional information and other advanced means of delay compensations to allow receiver compensation of time and position information in real time.

The Time Slot Interchanger ( TSI ) in the SM uses random-access memory to delay each speech sample to fit into a time slot which will carry its call through the exchange to another or, in some cases, the same SM.

IGRP uses bandwidth, delay, hop count, link reliability, load, and MTU.

Sound synthesis uses digital delay lines as computational elements to simulate wave propagation in tubes of wind instruments and the vibrating strings of string instruments.

RIP uses the hop count of the destination whereas IGRP takes into account other information such as node delay and available bandwidth.

He uses effect pedals such as the BOSTON HEAVY METAL, Dallas-Arbiter Fuzz Face, BK Butler Tube Driver, MXR KD IV Stereo Chorus, Vox CryBaby wah-wah, ToadWorks Barracuda flanger, Prescription Electronics Experience octave fuzz, Xotic AC Booster, MXR Flanger / Doubler, Electro-Harmonix Deluxe Memory Man delay, Boss Corporation DD-2 Digital Delay, MXR 1500 Digital Delay, Line 6 Echo Pro Studio Modeler, and up to two Maestro Echoplex tape delays.

In addition, the sponsor of the rival expedition sent to find the meteorite is called Blumenstein, is given the appearance of a stereotypical Jewish businessman and uses underhand and potentially lethal methods to delay Tintin's ship.

The sponsor of the rival expedition in The Shooting Star is the head of a major banking organisation, who uses unethical methods to delay the progress of Tintin and Haddock's ship.

Lord Desham, who is attracted to Jody, uses his influence to arrange for the young man to marry his WREN fiancée without the customary delay.

Since testicular growth is typically the first physical sign of true puberty, one of the most common uses is as confirmation that puberty is beginning in a boy with delay.

While this system generally uses delay as the basis for its measurements, the particular measurements and statistical methods vary depending on the facility being described.

An alternative echo system was the so-called " oil-can delay " method, which uses electrostatic rather than electromagnetic recording.

* By the fairness criterion it uses: max-min, proportional, " minimum potential delay "

He uses Gibson Dirty Fingers Humbucking Pickups, the same bridge pickup Tom uses in all of his signature ES-333 models, in order to emulate Delonge's signature distorted, over driven tone when playing hand muted octave chords, often with delay effects.

With Earthlings ?, he uses his 1958 Fender Stratocaster or his 1972 double cutaway Gibson Les Paul through a tuner, a distortion Rat pedal, Cry Baby, BOSS Digital delay, Phase 90 into a Silvertone Twin 12 and Fender Super Reverb amplifiers.

A multi-channel analyzer derives the gate pulse from a const-fraction discriminator and uses a fixed delay for a third copy of the original signal to account for the delay in the discriminator.

A delay embedding theorem uses an observation function to construct the embedding function.

uses queueing delay instead of loss probability as a congestion signal.

He also uses reverb and delay effects of his signature series Zoom G2R effects processor, which is connected in the effects loop of the amplifier.

XCOM uses a bottom-up parsing method, in which the compiler can delay its decision about which syntax rule it has encountered until it has seen the rightmost end of that phrase.

The delay is characteristic of more modern, technical freestyle, which uses the delay to perform more complicated maneuvers like turnovers and “ against the spin ” moves ( manipulations that use angle and carefully applied friction to force the disc in a direction that its spin counteracts, a technique invented and mastered by Skippy Jammer ).
