7-465: The Werkstatt-Ø1 is an educational tool and a compact analog synthesizer from Moog . It was designed to give people a thorough understanding of how synthesizers work. There is only one oscillator with a frequency control allowing tuning from 8Hz up to 16kHz, and a 4-pole ladder filter with cutoff and resonance control. To assemble the Werkstatt-Ø1 you have to screw the printed circuit onto
14-477: A drawing or signature made by the sender at the receiver's station. It was the first such device to transmit drawings to a stationary sheet of paper; previous inventions in Europe used rotating drums to make such transmissions. An analog synthesizer is a synthesizer that uses analog circuits and analog computer techniques to generate sound electronically. The analog television encodes television and transports
21-454: A metal chassis. Analog device Analog devices are a combination of both analog machine and analog media that can together measure , record , reproduce, receive or broadcast continuous information , for example, the almost infinite number of grades of transparency , voltage , resistance , rotation , or pressure . In theory, the continuous information in an analog signal has an infinite number of possible values with
28-479: The behavior of another physical system, or mathematical function. Modeling a real physical system in a computer is called simulation. The chemical reactions in photographic film and film stock involve analog processes, with camera as machinery. In electronics, a digital-to-analog converter is a circuit for converting a digital signal (usually binary) to an analog signal (current, voltage or electric charge). Digital-to-analog converters are interfaces between
35-425: The only limitation on resolution being the accuracy of the analog device. Analog media are materials with analog properties, such as photographic film , which are used in analog devices, such as cameras . 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
42-453: The picture and sound information as an analog signal, that is, by varying the amplitude and/or frequencies of the broadcast signal. All systems preceding digital television, such as NTSC, PAL, and SECAM are analog television systems. An analog computer is a form of computer that uses electrical, mechanical, or hydraulic phenomena to model the problem being solved. More generally an analog computer uses one kind of physical quantity to represent
49-416: 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 speedometer . The telautograph is an analogue precursor to the modern fax machine . It transmits electrical impulses recorded by potentiometers to stepping motors attached to a pen, thus being able to reproduce
