in which the value of a data item (such as time) is represented by a continuously variable physical quantity that can be measured (such as the shadow of a sundial)
A term used to describe a signal, such as the human voice, whose value varies continuously with time; or a transmission method, such as the traditional telephone network, which carries source signals as electrical waves Compared with digital systems, an analogue telephone line carries data at low speed; it also requires a modem to convert the computer's digital output into a form (sound) which it can handle
Voltage controlled as opposed to pulse controlled Analogue sound can more easily be used to accurately represent the original sound that it recorded than digital can The disadvantage is that analogue has more imperfections in the sound
A system in which one continuously-varying physical quantity (e g the intensity of a sound wave) is represented directly by another (e g the voltage of an electrical signal) as faithfully as possible
A continuous electrical or radio signal, usually represented simplistically by a sine wave An analogue signal has the properties frequency, amplitude, and polarization
Traditional methods of recording onto tape or reel-to-reel machines are known as analogue recording Analogue recording means that the recorded signal has a direct correspondence with the way the recording is created on the specific medium i e it can be used to bias a signal used to transfer magnetic information to the tape Digital recording on the other hand takes snapshots or samples of the analogue stream at various moments in time and pieces together the music from these samples The reduced (finite) amount of data that results can be more easily manipulated by machine (i e computer) although the battle still rages over which format or medium is the "best" for any given recording circumstance Back
The technology which until recently was the norm for mobile phones A transmission method or way of sending voice, video and data using signals (such as electricity or sound waves) that are continuously variable rather than discreet units as in digital transmissions In the context of wireless communications, analogue refers to transmission networks built in the 1980s and that use analogue technology rather than digital See also Digital Any kind of information (eg sound speech, pictures) is transmitted in continuous waveforms which the human senses are able to receive and to interpretate
A story that contains similar characters, situations, settings, or verbal echoes to those found in a different story Sometimes analogues reveal that one version was adopted from or inspired by another, or that both tales originate in a lost, older text When one version is clearly the ancestor of another, literary scholars refer to it a "source " In other cases, analogues appear that probably have no direct connection to each other Grettir's Saga, which includes a wrestling bout between the strongest Icelander and an evil spirit, is often thought of as an analogue to Beowulf, in which a man with the strength of thirty men wrestles with Grendel Grettir dives under an ocean-side waterfall and does battle with a Troll-wife, while Beowulf dives into a lake and does battle with Grendel's mother These two pairs of scenes are analogues to each other
Anything that has shades of meaning, a 'spectrum' of options or which changes gradually and 'smoothly' (like the undulations in a line of hills, for example) is referred to as "analogue" - as compared to anything which offers just two options (e g on/off, yes/no), which is referred to as "digital"
A signalling system that can take an infinite number of values This is often described by a mathematical sine curve An example of an analogue scale is temperature measurement, c f digital Close this window
A signal which can take on a continuous range of values between a minimum and a maximum value; method of transmitting information by continuously variable quantities, as opposed to digital transmission, which is characterized by discrete 'bits' of information in numerical steps
Relating to a mechanism in which data is represented by continuously variable physical quantities Quantities in two separate physical systems having consistently similar relationships to each other are called analogous One is then called the analogue of the other The electrical output of a transducer is an analogue of the vibration input of the transducer as long as the transducer is not operated in the non-linear (overloaded) range This is in contrast to a digital representation of the vibration signal, which is a sampled and quantised signal consisting of a series of numbers, usually in binary notation
Continuous change over time: continuous movement An example is the light dimmer switch in contrast to an ordinary light switch which is either on or off (digital)
The term for anything and everything we see in the real, non-computerised world Technically, it is a continuously variable signal This is the direct opposite of digital data, which is organised in individual, sharply delineated steps PCs do not handle analogue signals so they are converted to digital for processing
Analogue refers to signals that can represent an infinite range of numbers, as opposed to digital which can only be distinct whole numbers Analogue data often comes from measurements, like a sine wave The sound a modem makes over the phone is analog since it can be any of a number of different frequencies The fixed-line networks usually transfer analogue data and fax The GSM networks are Digital
A form of data display in which values are shown in graphic form such as curves Also a form of computing in which values are represented by directly measurable quantities such as voltages of resistances Analogue computing methods contrast with digital methods in which values are treated numerically
A transmission method or way of sending voice, video and data using signals (such as electricity or sound waves) that are continuously variable rather than discreet units as in digital transmissions In the context of wireless communications, analogue refers to transmission networks built in the 1980s and that use analogue technology rather than digital Back to the top
usually a semantic or narrative feature in one work said to resemble something in another work, without necessarily implying that a cause-and-effect relationship exists (as would be the case with source and influence) For example, Beowulf's battle with the Dragon is analogous with the fight between the Red Cross Knight and the Dragon in Book I of Edmund Spenser's The Faerie Queene
Analogue is an adjective used to describe things that are continuous Think of the two types of stereo system volume control for comparison With some, turning to raise or lower volume is smooth This is analogue With others, as you turn, the knob clicks between low and high;there's no setting in between the clicks This is digital (Thedigital side may offer only 10 choices, say, but is very accurate )
Analogue technology involves measuring, storing, or recording an infinitely variable amount of information by using physical quantities such as voltage
something having the property of being analogous to something else of a circuit or device having an output that is proportional to the input; "analogue device"; "linear amplifier
" An organ which is equivalent in its functions to a different organ in another species or group, or even in the same group; as, the gill of a fish is the analogue of a lung in a quadruped, although the two are not of like structural relations
{i} something which has a similarity to something else; organ or part which functions in a similar manner or the same as an organ or part of another but its structure and evolutionary origin are different (Biology); chemical compound that has a similar structure to another but differs in its composition (Chemistry)
A species or genus in one country closely related to a species of the same genus, or a genus of the same group, in another: such species are often called representative species, and such genera, representative genera
An organ which is equivalent in its functions to a different organ in another species or group, or even in the same group; as, the gill of a fish is the analogue of a lung in a quadruped, although the two are not of like structural relations
