This circuit consists of a large array of memory cells composed of a transistor and some other circuitry. Because digital signals have only a finite set of states, they are amenable to error-correction techniques; this feature gives digital electronics its principal advantage over analog electronics. electronics (countable and uncountable, plural electronics) The study and use of electrical devices that operate by controlling the flow of electrons or other electrically charged particles or by converting the flow of charged particles to or from other forms of energy. In many cases, no more than three dust particles of less than 1 micrometer in diameter are acceptable per cubic meter. Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electrons in vacuum and matter. Electrical vs Electronics. A. Chernyshev, and M. M. Bogoslovskii. Electricity is defined as “of, relating to, producing, or operated by electricity” (1). n. 1. The areas of application of solid-state electronics also include dielectric electronics, magnetoelectronics, acoustoelectronics, piezoelectronics, cryoelectronics, and the development and manufacture of resistors. As electronics develops and the technology of the production of electronic devices improves, the range of application of electronics will expand in all areas of human life and activity, and the role of electronics in accelerating scientific and technical progress will grow. Electronic methods and equipment are used in biology in the study of cells and the structure and responses of living organisms and in medicine in diagnostics, therapy, and surgery. Quantum electronics devices serve as the basis of instruments used for the accurate measurement of distances (range finders), quantum frequency standards, quantum gyroscopes, optical-frequency multichannel communication systems, long-range space communication systems, and radio astronomy.
