Electrical device. Electric (al) devices are devices that functionally rely on electric energy ( AC or DC) to operate their core parts ( electric motors, transformers, lighting, rechargeable batteries, control electronics ). They can be contrasted with traditional mechanical devices which depend on different power sources like fuels or human ...
A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators. Semiconductor devices have replaced vacuum tubes in most ...
Electronic component. Various electronic components, with a 15 cm ruler to scale. An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to ...
A single semiconductor device crystal can have many p- and n-type regions; the p–n junctions between these regions are responsible for the useful electronic behavior. Using a hot-point probe, one can determine quickly whether a semiconductor sample is p- or n-type. [6]
Electronic devices have hugely influenced the development of many aspects of modern society, such as telecommunications, entertainment, education, health care, industry, and security. The main driving force behind the advancement of electronics is the semiconductor industry , which in response to global demand continually produces ever-more ...
Sample and hold. In electronics, a sample and hold (also known as sample and follow) circuit is an analog device that samples (captures, takes) the voltage of a continuously varying analog signal and holds (locks, freezes) its value at a constant level for a specified minimum period of time. Sample and hold circuits and related peak detectors ...
A PCs power supply is an example of a piece of power electronics, whether inside or outside of the cabinet. Power electronics is the application of electronics to the control and conversion of electric power . The first high-power electronic devices were made using mercury-arc valves. In modern systems, the conversion is performed with ...
Examples of electromechanical sound producing devices include the telharmonium, Hammond organ, electric piano, and the electric guitar. Purely electronic sound production can be achieved using devices such as the theremin, sound synthesizer, and computer. [2] Genre, however, is not always dependent on instrumentation.
