Electronics Top Facts

Electronic music
Electronic music is music that employs electronic musical instruments and electronic music technology in its production. In general a distinction can be made between sound produced using electromechanical means and that produced using electronic technology. Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, and the electric guitar. Purely electronic sound production can be achieved using devices such as the Theremin, sound synthesizer, and computer.

Series and parallel circuits
Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are called series and parallel and occur very frequently. Components connected in series are connected along a single path, so the same current flows through all of the components. Components connected in parallel are connected so the same voltage is applied to each component.

CE mark
The CE marking as it has been legally called since 1993 (per directive 93/68/EEC) (abbreviation of French: Conformité Européenne, meaning "European Conformity", formerly EC mark) is a mandatory conformity mark for products placed on the market in the European Economic Area (EEA). With the CE marking on a product, the manufacturer ensures that the product conforms with the essential requirements of the applicable EC directives.

IEEE Fellow
An IEEE member is elevated to the grade of IEEE Fellow for "unusual distinction in the profession and shall be conferred by the Board of Directors upon a person with an extraordinary record of accomplishments in any of the IEEE fields of interest". The number of members selected for elevation to Fellow in any year is limited to at most one-tenth of one percent of the total voting membership. The grade of Fellow first appeared in the AIEE constitution of 1912.

Electronic drum
An electronic drum is an electronic synthesizer which mimics an acoustic drum kit. The electronic drum usually consists of a set of pads mounted on a stand in a disposition similar to an acoustic drum kit. The pads are discs with a rubber or cloth-like coating. Each pad has a sensor which generates an electric signal when struck. The electric signal is transmitted through cables into an electronic module, which produces a sound associated to the selected pad.

Network analysis (electrical circuits)
A network, in the context of electronics, is a collection of interconnected components. Network analysis is the process of finding the voltages across, and the currents through, every component in the network. There are a number of different techniques for achieving this. However, for the most part, they assume that the components of the network are all linear. The methods described in this article are only applicable to linear network analysis except where explicitly stated.
