MOS motion picture
Analog photography, also known as film photography, is a term usually applied to photography that uses chemical processes to capture an image, typically on paper, film or a hard plate. These processes were the only methods available to photographers for more than a century prior to the invention of digital photography , which uses electronic ...
Obsolete name for an ammeter; now an instrument for measuring fluid viscosity. rheostat Obsolete name for a two terminal variable resistor, usually with a rotating shaft to allow manual or motor driven adjustment. right-hand rule A mnemonic device for remembering the definitions of the directions of current and magnetic field in generators. ripple
Device that changes digital signals to analog, or reconstructs information (data) by performing the inverse (reverse) functions of an encode process. [1] Definition The aggregate of fine details available on-screen. The higher the definition of an image, the greater the number of details [that can be discerned by the human eye or displayed].
There are notable non-electrical analog devices, such as some clocks (sundials, water clocks), the astrolabe, slide rules, the governor of a steam engine, the planimeter (a simple device that measures the surface area of a closed shape), Kelvin's mechanical tide predictor, acoustic rangefinders, servomechanisms (e.g. the thermostat), a simple mercury thermometer, a weighing scale, and the ...

Analog image processing is the use of an optical computer to process physical, optical images [1] formed by light waves coming from an object, as opposed to the digital image processing [2] and its use of digital computers to process pixelated, digital images. Correspondingly, a range of digital image processing techniques possess direct ...
An analog signal uses some property of the medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information. In an electrical signal, the voltage , current , or frequency of the signal may be varied to represent the information.
