Electrical and mechanical engineering involves the production, distribution, processing, storage and conversion of electrical energy to and from other energy forms (using wires, motors, generators, batteries, switches, relays, transformers and other components. passive). This difference began this year. In 1906, it was invented by Forest Le of the Triode, which amplified the weak radio and audio signals. The “radio technology” because of its principle is the design and theory of radio transmitters, receivers and vacuum tubes.

In 2018, most electronics use semiconductor components to control electrons. The study of semiconductor devices and related technologies is a branch of solid state physics. This article focuses on engineering.

Electronic components are physical entities in electronic systems that affect electrons or related fields in a manner consistent with the intended function of the electronic system. Components are generally intended to be connected normally by soldering to printed circuit boards (PCBs) to create electronic circuits with specific functions. (For example, a radio amplifier or generator). Components can be individually packed or in more complex parts, such as integrated circuits. Components are usually classified as active (such as transistors and transistors) or passive (such as resistors, diodes, inductors and capacitors).

Electronic circuits, such as vacuum tubes, transistors, diodes, integrated circuits, optoelectronics and sensors, electrical components and connectors. In general, electronic devices are primarily circulated or, in particular, by active semiconductors, which are complemented by passive components. The circuit is described as an electrical circuit.

A digital circuit is an electrical circuit that depends on the total number of voltage levels. Digital circuits are the physical representation of boolean algebra and are the basis of all digital computers. For most engineers, the word “Digital circuits”, “digital systems” and “logic” can be used interchangeably in the context of digital circuits. Logic 0 is usually a lower voltage and is called “low”, while logic “1” is called. “High”. However, some systems use reverse definition (“0” and “High”) or are running. Often, logical designers can recognize these definitions from circuit to circuit as they deem appropriate for design. Level definitions are “0” or “1”.
