In biochemistry, a substance which similar, but not identical, to a different.
1. an occurance that has varied task. 2. something that looks like like an authentic product.
chiefly U.S. spelling of analogue (q.v.).
1. Information research: (1) Phenomenon that varies infinitely over an assortment. Like, throughout the very early section of on a daily basis sunlight slowly increases in brightness in a smooth flow after which reduces in the same manner in later part. At a moment, the sunshine is either just about bright as compared to preceding and succeeding moments. In comparison, an area lit by an electric light bulb is both dark or lighted at a minute, dependent on whether or not the existing is started up or down. Likewise, the colors and colors in a film-photograph or a painting merge effortlessly into neighboring colors and tones, whereas an electronic digital photo (or a scanned painting) consist of tiny dots all of which can be distinct and split from the neighbor. (2) Correspondence or resemblance associated with the backup (facsimile or representation) of a product aided by the product it self. A chart or graph, drawing, photocopy, photo, picture, or scale model 'looks like' (is 'analogous to') the movement of rates, layout of a building, the first document, face of someone, the shape of a device the 'thing' it represents. Likewise, analog products reflect (in one single way or perhaps the other) the amounts they measure: a mercury thermometer reveals a column of mercury which proportional towards the temperature it checks out; the 'second' hand constantly sweeps the face area of a wrist watch and represents the unbroken flow period, the needle of an automobile's gas gauge shows amount of fuel in tank by pointing to a corresponding degree on a scale. In conclusion, analog information is (a) constant, (b) measured, and (c) exact (unlike accurate). 2. Communications: One of just two techniques (another is 'digital') of transforming information into electrical indicators. Analog signals tend to be constant waves and correspond in magnitude (just about, high or reduced) towards quantities they represent. As an example, an analog cell phone converts sound waves into identical electric waves that are reconverted into noise at the receiving end. Becoming identical (analogous) to electric indicators produced in nature, analog indicators tend to be extremely prone to interference from normal event (such as for example climate and sunshine places) that cause signal distortion, loss, and sound. Analog signals degrade with distance and repeated duplication but, for similar quantity of information, need less bandwidth for transmission as compared to electronic indicators. 3. Processing: Representation of data by a literally measurable volume which proportional toward information becoming represented. An analog computer converts information into a corresponding current for information handling, storage space, and transfer. For instance, a temperature reading (state, 30°C) might represented by an electrical present of 2.5 volts, and twice as high reading (60°C) by 5.0 volts.
some thing having the residential property of being analogous to something different
- of a circuit or device having an output that's proportional to your input
Analog or analogue is an electric communication delivered as indicators of differing frequency rather than ON or OFF like an electronic information transmission. Analog allows gear to take care of information that continuously changes particularly current, present, and wave. The image is a good example of an analog sign or exactly how analog are represented. Within the exemplory instance of a wave, it's a high and reduced price with numerous values in-between. With an electronic digital wave, it might have increased or price with a nothing in-between.
- analog [Am.]
As people, we perceive society in analog. Every little thing we come across and notice is a continuous transmission of data to the senses. This constant stream is really what describes analog information. Digital information, however, estimates analog information only using people and zeros. For example, a turntable (or record-player) is an analog device, while a CD player is digital. The reason being a turntable reads lumps and grooves from accurate documentation as a continuing sign, while a CD player just reads a few people and zeros. Likewise, a VCR is an analog product, while a DVD player is electronic. A VCR reads audio and video from a tape as a continuous blast of information, while a DVD player just reads people and zeros from a disc. Since electronic devices read only people and zeros, they are able to only approximate an audio or video signal. This implies analog information is actually much more precise than electronic information. However, digital information can can be controlled simpler and maintained a lot better than analog data. More importantly, computers is only able to manage digital information, which explains why many information these days is saved digitally. However, if you need to move video from old analog movie tapes into your computer system to modify them, you aren't away from chance. You should use an electronic to analog converter (DAC) to convert the analog information into a digital sign that may be acquiesced by your personal computer.

It is sometimes an effective way to integrate limited analog functionality with mainly logic functions.
