A description of a continuously variable signal or a circuit or device designed to handle such signals. The opposite is discrete or digital.
may refer to:
- Analogue (literature), a literary work that shares motifs, characters or events with another, but is not directly derived from it

Analog Science Fiction and Fact is an American science fiction magazine. , it is the longest running continuously published magazine of that genre, the June 2015 issue being number 1,000. Initially published in 1930 in the United States as Astounding Stories as a pulp magazine, it has undergone several name changes, primarily to Astounding Science-Fiction in 1938, and Analog Science Fact & Fiction in 1960. In November 1992, its logo changed to use the term "Fiction and Fact" rather than "Fact & Fiction". It is in the library of the International Space Station. Spanning three incarnations since 1930, this is perhaps the most influential magazine in the history of the genre. It remains a fixture of the genre today.

In chemistry, a substance that is similar, but not identical, to another.
The traditional method of transmitting voice signals where the radio wave is based on electrical impulses, which occur when speaking into the phone. Most cellular companies today transmit in analog.

An audio signal is an electrical representation of, i.e., is analogous to, a sound waveform. The signal's voltage fluctuates in the same pattern as the speaker cone that reproduces it. Analog synths use oscillators, filters, amplifiers and other electrical components to create electrical signals analogous to the audio wave forms they are trying to represent.
A form of information which is represented by a continuous electromagnetic wave encoded so that its power varies continuously with the power of a signal received from a source (e.g., a source of sound or light). Contrast to digital. A signal in which the characteristic quantity representing information may at any instant assume any value within a given range. Transmission employing variable and continuous waveforms to represent information values.
Analog, Pressure-sensitive (like the gas pedal of a car). Most console controllers have analog control sticks. Some feature analog buttons.
Data (signal) presented in a non-digital, continuous form.
variant of analogue.
An electrical signal that continuously varies in strength as related to some form of input. A continuous signal that requires time to make a transition from one level to another. Standard audio and video signals are analog. Both can be digitized. The video in the laserdisc format is analog composite. The audio can be present in both analog and digital forms. Both the audio and video on DVD has been recorded on the disc in the digital domain. The alternate, British spelling of the word analogue is often used in the audio world.
The ability to quantify or measure continuous changes in volume, speed, mass or other physical properties through empirical data.
In chemistry, a compound with a structure similar to that of another compound but differing from it in respect to certain components or structural makeup, which may have a similar or opposite action metabolically.
a signal in an electrical circuit that can have a continuous range of values. See also, digital.
waveforms, with valleys and ridges, referring to the natural form of sound/audio. To store/playback on a computer, analog data is converted to digital data.

Designs, manufactures and markets high-performance linear, mixed-signal and digital integrated circuits, including analog-to-digital and digital-to-analog data convertors and amplifiers, voltage references, and general purpose application devices, which address wide range of real-world signal processing applications in
Capable of exhibiting continuous fluctuations. In an analog audio system, fluctuations in voltage correspond in a one-to-one fashion with (that is, are analogous to) the fluctuations in air pressure at the audio input or output. In an analog synthesizer, such parameters as oscillator pitch and LFO speed are typically controlled by analog control voltages rather than by digital data, and the audio signal is also an analog voltage. Compare with digital.

Almost everything in the world can be described or represented in one of two forms: analog or digital. The principal feature of analog representations is that they are continuous. In contrast, digital representations consist of values measured at discrete intervals.
Digital watches are called digital because they go from one value to the next without displaying all intermediate values. Consequently, they can display only a finite number of times of the day. In contrast, watches with hands are analog, because the hands move continuously around the clock face. As the minute hand goes around, it not only touches the numbers 1 through 12, but also the infinite number of points in between.
Early attempts at building computers used analog techniques, but accuracy and reliability were not good enough. Today, almost all computers are digital.
The readout of an instrument by a pointer (or other indicating means) against a dial or scale.
A continuously variable signal. A mercury thermometer, which gives a variable range temperature readings, is an example of an analog instrument. Opposite of digital.
Continuously variable signals or data.
Refers to systems that represent or encode or transmit information in a manner that is continuously variable, specifically not having to be rounded up or down to certain numeric values or being restricted to discrete pixel positions on a line. An analog picture reproducing system for example might reproduce any shade of red from a dark brown to a light pink while a non-analog system might only have twenty specific shades of browns, reds, and pinks to choose from. NTSC video is analog in the horizontal direction; details can occur anywhere along a scan line. It is not analog in the vertical direction; details that "fall between" two scan lines are lost or show up shifted slightly to fit on one of the scan lines.
Something is Analog if its changes are represented by something else changing eg. The higher the mercury rises in a thermometer the warmer it is. Analog systems in PC terminology refer to the use of variable voltage in electrical signals to represent any kind of data.
