Analogue electronics - Wikipedia, the free encyclopedia Analogue electronics are those electronics systems with a continuously variable signal. Analogue is usually thought of in an electrical context, but mechanical, pneumatic, hydraulic, and other systems may also use analogue signals. Any information may be conveyed by an analogue signal, often such a signal is a measured response to changes in physical phenomena, such as sound, light, temperature, position, or pressure, and is achieved using a transducer. en.wikipedia.org /wiki/Analog_Electronics   (488 words)

Electronics - Wikipedia, the free encyclopedia The field of electronics is the study and use of systems that operate by controlling the flow of electrons (or other charge carriers) in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the field of electronics engineering, and includes the hardware design side of computer engineering. The main uses of electronic circuits are the controlling, processing and distribution of information, and the conversion and distribution of electric power. en.wikipedia.org /wiki/Electronics   (1205 words)

Components in Electronics - CIE In the field of analogue electronics, the pain of achieving precision is the need for calibration Dr. Les Landsberger of Microbridge Technologies introduces a passive, VLSI- and MEMS-compatible adjustable micro-resistor that promises to numb the pain. In general, electronic circuits, systems and solutions, both integrated and discrete, are prone to variations in parameter values of their components. As a result, analogue electronics relies on a variety of circuit design, calibration and adjustment techniques, to overcome these variations, and achieve the required performance and precision. www.cieonline.co.uk /cie2/articlen.asp?pid=&id=5463   (1683 words)

Introduction to Digital Electronics - Lesson 1 Digital electronics is the sort of electronics that is used in computers and similar pieces of equipment, such as mobile phones, that does complicated processing on information. Analogue electronics uses voltages that can be any value (within limits, of course - it's difficult to imagine a radio with voltages of a million volts!) The votlages often change smoothly from one value to the next, like gradually turning a light dimmer switch up or down. Because of this, analogue signals inevitably build up noise as they get older, and this is the reason that old records sound scratchy and that old video recordings are unwatchable. richardbowles.tripod.com /dig_elec/chapter1/chapter1.htm   (1502 words)

Digital Electronics: Basic concepts and principles A description of what we mean by digital electronics is, strangely, best approached from a description of what it is not. An analogue signal is a fluctuating voltage which can have any numerical value. Using patterns of these "two state" signals we are getting back to the ability that analogue signals have in representing a bigger range of values. www.pc-control.co.uk /digital_electronics.htm   (656 words)

Phil Thomas career profile As a teenager I had a general interest in electronics, music and I was fascinated by most things relating to science and technology.

BBC - Education Scotland - Higher Bitesize Revision - Physics - Electricity and electronics - Analogue electronics: ... Analogue electronics uses electrical signals that are continually changing to represent some physical quantity such as the loudness of a sound. The main circuit element used in analogue electronics is the operational amplifier (op-amp). If the temperature of the thermistor increases, the voltage at the inverting input falls and the output voltage changes to +15 V and so the bell rings. www.bbc.co.uk /scotland/education/bitesize/higher/physics/elect/analogue1_rev.shtml   (355 words)

Marc's Technical Pages: Power Quality Symptoms and Solutions - Analogue vs. Digital The primary difference between analogue and digital is analogue is the physical reaction of an input signal. This may appear a little strange to have a digital process between two analogue points being the input and the display, but this is done when certain calculations are required between the input and display, e.g. With digital electronics, numbers transferred from one section to another depend mainly on the number of "bits" available (a 'bit' is a binary digit). www.marcspages.co.uk /pq/4220.htm   (1834 words)

The number of different analog circuits so far devised is huge., especially because a ´circuit´ can be defined as anything from a single component, to systems containing thousands of components. Analogue circuits are sometimes called linear circuits although many non linear effects are used in analoge circuits such as mixers, modulators etc. Good examples of analog circuits are valve or transistor amplifiers, operational amplifiers and oscillators. www.zdiamond.net /articles/Electronics   (1137 words)

Digital-to-analog converter   (Site not responding. Last check: 2007-09-10) In electronics, a digital-to-analog converter (DAC or D-to-A) is a device for converting a digital (usually binary) code to an analogue signal (current, voltage or charges). DACs are used in analogue signal processing circuits to replace potentiometers. They allow small adjustments to be made to the circuit by software, instead of the old technique of using a screwdriver. www.freedownloadsoft.com /info/dac.html   (1152 words)
