Electronics
Electronics deals with the field of electrical shipments (mobile electrons) of non-metallic conductors (often called semiconductors), while electricity term that refers to the flow of charge through the metal connectors. For example, falls flow of charge through silicon - which is one of nonmetals - under the framework of the "electronics" while falls flow of charge through the copper - which is one of the metals - under the framework of the "electricity". This has started to distinguish between these two terms for the first time in about 1906 when he invented "Lee de Forest" triode (Trayud). And until 1950 it was called the field of electronics called "wireless technology"; and because it was used primarily in the designs and theories for each of the transmitters and wireless receivers and vacuum tubes. Moreover, the study is the semiconductor technology and own one of the branches of physics, while the electronic design to solve practical problems a branch of electronics engineering and Binaaldoair. This article focuses on the engineering aspects of electronics.
Electronic components and devices
The electronic components is any physical entity in the electronic system and its function is to influence the electrons or related fields in a certain way consistent with the specific function of the electronic system. Overall, the manufacture of electronic components so that they are connected to each other - making them usually coalesce printed circuit board - in order to create an electronic circuit with a particular function (for example, for making amplifier or a radio receiver or a pulse generator). And electronic components can be found in the individual image or a simple collage image is more complex, such as those found in integrated circuits. This, and common examples of components Alaketronahalmktvat resistors and diodes (diode) and the transistor and so on.
Types of electronic circuits
(Analog circuits (Analog
The number of different analog circuits that have been designed so far are very significant, especially since the term "electronic circuit" could be called anything from a single component and even systems containing thousands of components. Sometimes, called analog circuits called "linear circuits" Although the use of many of the non-linear effects in analog circuits such as mixing and modulated devices and others. A good example is the analog circuit vacuum tube and transistor amplifiers and operational amplifiers and pulse generators. These days, used in some analog circuits or even sometimes a digital techniques Maekerobrosissour techniques (precision) treatment in order to improve the basic performance of the department. Frequently called on this type of circuit called "mixed-signal circuits." In some cases, it may be difficult to distinguish between digital and analog circuits; because they contain private linear and nonlinear operations elements. It is one example of this is "comparative" that pulls the extent of connected voltage (This analog circuit characteristics), but only one level out of two levels, as is the case in the digital circuit are described later. Similarly, the amplifier transistor when it is running at a high effort for him to acquire the attributes of the key that is controlled and therefore, it has two levels of Kherj.ttkon most analog devices, such as wireless receivers, from the collections of the basic circuits. And using analog circuit voltage range of the caller, not separated as in digital circuits.
(Digital circuits (Digital
The digital circuit is based on a number of levels of voltage discrete circuits. It is also considered the most practical application
Common rules of algebra Alboulini and the basis of all digital computers. For most engineers, the "digital circuit" terms and "digital system" and "logic" terms used mutually in the context of talking about digital circuits. For digital circuits is used mostly two levels of voltage they are called "low" (0), and "high" (1). Often the level of voltage "low" when it is close to zero and be "high" when more than this, and this depends on the voltage used. It should be noted here that some prototypes of computers based on the so-called triple logic that contains three logical levels and not just a two-tier work.
Each of the computers, watches and electronic control devices of programmable logic consists (used to control industrial processes) of digital circuits. Units Digital signal processing is also another example of that. Construction elements in electronic devices
