Power Electronics
People began experimenting with electricity, when Thales of Miletus found that wool coating on amber would make them attractive.Since the 1900's, devices have used glass or metal panels to control the flow of electricity. With these components low power can be used to replace one. This changed the radio, allowing for more inventions.
In the 1960s and early 1970s transistors and semiconductors began to replace vacuum tubes. Transistors can be made much smaller than vacuum tubes and can operate using less power.
At about the same time, composite circuits (circuits with large numbers of small transistors placed in small pieces of silicon) are widely used. Combined circuits make it possible to reduce the number of components needed to make electronic products and make products much cheaper in general.
What is Electronics
Electronics means the study of the flow of electrons in electrical circuits. The term Electronics comes from electron mechanics which means to study how the electron behaves under a variety of external use conditions. IRE - The Center for Radio Engineers has provided an electronic definition as "the field of science and engineering, dealing with electron devices and their use." Electronic foundations are a major topic in all branches of engineering these days.
Electronics are a study of how to control the flow of electrons. It operates in circuits made up of so-called components and connecting cables that control the flow of electricity and direct it to perform useful functions. The science behind Electronics comes from physics research and is used in practical ways in the field of electrical engineering.
Signal processing circuits within the television use light, color, and audible sound signals obtained to control the output devices of the television. The output device shown may be a cathode ray (CRT) tube or a plasma or liquid crystal display screen. The audio output device may be a magnetic-operated audio speaker. Display output devices convert the light of the processing circuit details and colors to the on-screen image display. An audio device converts used audio information into sounds that can be heard by the audience.
Most people can name many simple electronic devices, such as transistors, fuses, breakers, batteries, motors, transformers, LEDs and bulbs, but as the number of items starts to increase, it often helps to think. with small programs or blocks, they can be linked together to make something useful.
Use of Electronics
Electronics have made great strides in the last few decades and our daily lives include the use of technology. Electronics has played a major role in all aspects of our lives
Electronics is the science of electrical energy control, in which electrons play an important role. Electronic devices operate with electrical circuits that include electrical equipment such as vacuum tubes, transistors, diodes, integrated circuits, compatible electrical equipment, and connection technology. Typically, electronic devices consisting of circuits consisting primarily of or specifically functional semiconductors are fitted with inert materials; such a circuit is defined as an electrical circuit. Electrical equipment and its use are the best
Influence our daily life in such a way that it is impossible to spend even a few hours without them. From the beginning of the day until bedtime, we use dozens of electrical gadgets to make our job easier and solve our problems. From small alarm clocks to sophisticated computers, from mobile to cameras, from the kitchen to the bathroom, from the bedroom to the office, wherever electrical appliances can be seen. USE OF ELECTRONICS Aerospace Industry Today with the advancement of technology in the aerospace industry it has opened up many possibilities for humans. Electronics are widely used in.
Aerospace such as Space shuttle, Satellite electric power, flight power management. Even in commercial aircraft there are hundreds of instruments used to measure different physical properties such as temperature, pressure, altitude, etc. Electronic power plays a major role in space spaces and on satellites. They are all responsible for the empowerment and management. Medical - The advent of electronics, and especially computer technology has made it possible for doctors to diagnose His patient. Many devices such as x-ray, NMR etc. which are a combination of others
Physics theorem and electronics. Significant advances have been made in medical science. There are a few new developments that show the value of electronics - Robotic Check-Ups, Diabetes-free diabetes care, Electronic Aspirin
Analog circuits
The analog circuits used for signals have different amplitudes. Typically, analog circuits measure or control the magnitude of signals. In the early days of electronics, all electronic devices used analog circuits. The frequency of the analog circuit is usually measured or controlled using an analog signal. Even with the creation of many digital circuits, analog circuits will always be needed, because the earth and its people operate in analog ways.
Digital circuits
Digital circuits used for signals only open and close instead of frequent operation at intermediate and external levels. Functions in digital circuits usually have one signal level when turned on, and another signal level when turned off. Generally, in digital circuits something is only opened again
