Specialization of Electronics

       With out any doubt the Electronics revelation in this technologic age is very important. Most people now a days need a different kinds of Electronics devices, at home,  at school, at university, in hospital, and even in the street. Most people deal with electronics with different  ways, which leads me to talk about my major.

        Electronics are a forked major, but my specialization in general is industrial electronics & Control. in this major we work and deal with the electronics devices. The engineer must know and study what set contain. Starting from the main circuit through the components, the correct connection, and ending with functions and diagrams.

           There are many important electronic circuits, but I am going to talk about the radio circuit, because it's simple and one of the main circuit in electronics devices. The radio contain six progress steps: tuner, detector, AC amplifier, volume control, power amplifier, and speaker. Every circuit of these steps has special components that control the signal, the wave, and the value. Almost every component in each electronic circuit have a special function.

              Knowing the function of each component is very important, because if the engineer needs to repair and fix the device, he must know what the path of  the signal in the circuit is and what function of each component is. If one of the functions is not working he can go back and check for the components of the circuit which  caused the defective function.

          There are a huge number of different kinds of components. But the more important and more common of these circuits are: A resistor, and there is more than one kind of it. The function of the resistor is usually to resistant and protect the citcuit from the high voltage and currents. A transformer, it's for transforming the current from low to high and vice versa. A capacitor, it's to clear the waves and the signals and store the extra current.
