An analog signal is any continuously variable signal; it differs from a digital signal in that small fluctuations in the signal are meaningful.
To understand analog, you really have to understand digital as well. Analog is an adjective used to describe things that are continuous. Think of the two types of stereo system volume controls for comparison. With some, turning to raise or lower volume is smooth. With others, as you turn, the knob clicks into several stops between low and high; there's no setting in between. The smooth turning is analog, offering infinite variations between 1 and 10. The digital side offers only 10 choices, but is highly accurate. Unfortunately, you've learned the downside of analog if ever you've copied an audio or videocassette and noticed the degradation in quality from first generation to second.[See Also: Digital

1) An analog cassette tape (eg - maxell XL2) 2) Analog is a direct, physical representation of a wave form. Because of this, it is possible to go slightly over 0db while recording in analog - it'll sound more dynamic, in fact, if you go a little over. the downside is that the accuracy of this representation is dependent on the medium upon which it is recorded. That is why something like a Maxell XL2 is better than some cheap tape - the Maxell tape formulation works better at capturing the wave form accurately.

The analog signal is converted back into a digital form before delivering it to a destination computer.
A conventional TV signal, industry standard for more than 50 years.
A way of sending data in which the signal is similar, or analogous, to the original signal. Analog signals are continuos expressions of electricity, as opposed to digital signals in which there is an alternating absence and presence of signal.
When a signal is continuously variable, it is analog. When a signal is broken into units that are rounded to discrete values, it is digital. Analog signals contain "all of the data" but it is prone to interference and degradation. It is not possible to catch and remove all of the interference from an analog signal and so the quality declines as it travels to your TV. With a digital signal, certain values are expected. When a value is received that is not within the expected range, it can be filtered or adjusted. This ability to detect and filter or repair a digital signal makes it possible to deliver a signal to your TV that is as good as when it left the studio.
In telephone transmission, spoken words are transmitted as analog sound waves or frequencies (as opposed to digital signals). Until the late 1960s, all telephone calls were analog. Now, while most phone companies are digital, there are still many sections of telephone networks that use analog service, including the majority of home telephones that plug into jacks and the telephone lines from homes to the nearest phone company equipment.

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.
True representation of an object or signal. Voice and music are analog, in other words they represent the true characteristics of the sound, in a waveform that matches the amplitude (loudness) and frequency (tone). Analog information must be transformed into a digital signal in order to be processed by the computer. Music, such as an MP3 recording, is first recorded from its analog format into a digital signal by your sound card which has an analog-to-digital (A/D) converter. It is then stored on the disk or CD. To play it back, the sound card must convert the digital signal back into an analog signal by means of a D/A converter so that it can be sent to the speakers which are analog devices. Since sound is a waveform and digital signals are a series of ones and zeros, it is important that the A/D and D/A converters can sample the waveform a high number of times in order for the sound to be "pure." MP3 recorders offer a variety of recording "sample rates," like 96 Kbs, 128 Kbs, etc. The higher the sample rate, the better the quality, but the larger the file. A good choice, if size is not too much of a problem, is 128 Kbs.
Analog refers to a representation of a quantity that varies over any continuous range of values. Analog signals can be thought of as pure in nature and...

Analog networks are subject to interference, relatively low in reproduction quality, and not able to handle large quantities of data. The analog network is rapidly being replaced by a Digital Network.

A transmission or process method using a series of continuous waves. A typical analog device is a clock in which the hands move continuously around the face and thus is capable of indicating every possible time of day. In contrast, a digital clock is capable of representing only a finite number of times (every tenth of a second, for example). Other examples of analog technology are phone transmissions and television broadcasts.
An audio signal that is an electrical replica of the waveform of the sound it represents. Most car stereo components are analog in nature, CD players are the exception.

Pertaining to measurements or devices in which the output varies continuously, i.e. voltage or rotation signals. Compare to digital.
Comes from the word "analogous," which means "similar to." In telephone transmission, the signal being transmitted-voice, video, or image-is analogous to the original signal. In other words, if you speak into a microphone and see your voice on an oscilloscope and you take the same voice as it is transmitted on the phone line and run that signal into the oscilloscope, the two signals would look essentially the same.

analog content: content that uses a mechanism in which data are represented by continuously variable physical quantities (e.g., frequency and amplitude of sound recorded on tape, image printed on film). analog storage media: stores analog content (e.g., paper, photographic paper or negative, film, microfilm, audio tape, VHS tape, vinyl records, stone, cave wall). To be used in computers, analog content must first be converted into a binary code. Such content that has been converted is often referred to as digitized. Digitizing is the "sampling" of an analog signal or content at predetermined interval locations; the signals are then converted into binary (1,0) form (digital). The closer the intervals, the more closely the digital signal represents the analog signal.
A signal that varies or modulates; wired telephone systems use an analog system to covert voice into an electronic signal. (See also digital.)

An adjective used to describe a method of converting audio and video information to a continuously varying voltage or magnetic field representing the original data. The term is used mainly to differentiate established data storage methods of the 1960s and 1970s from the newer digital storage methods.

For synthesizers, this means that there is real electricity running through it's veins - and that it is an analogous form of energy (electrical voltage) that will eventually come out at the speaker as sound. These signals are generated by an oscillator. Other electrical components can shape (envelope) and color (filter) the signal. The signal is prone to distortions which we usually percieve as a warm and sweet tone! Any synthesizer, new or old, that uses VCOs can be considered analog.

Launched in the U.S. in October 1983, this is the original form of cellular service. This service uses a waveform transmission instead of the zeros and ones that a digital system uses.
