A Handbook of Communication Electronics

he principles and applications of Electrical and Electronics Engineering and its importance is to evince interest on the topics so that the students gets motivated to study the subject with the interest. The Electrical/Electronics Technology program at SPCC is designed to provide training in the installation and maintenance of electrical/electronic systems found in residential, commercial and industrial facilities. Electrical technology deals with all machines, tools, devices and systems in which a current or a flow of electrons takes place through conductors and metals. It involves the design and development of high-voltage systems and components such as motors, generators, heaters, electrical power transmission and distribution systems, radio wave and optical systems, converters, and control systems for operating light and heavy machinery.

The source of electric power in our houses, offices and class rooms is the AC source. A single source works as voltage and current source. Systems like Radio, TV and Music have inbuilt dc powers supply that converts ac in to dc to supply power to these and we enjoy programmes of our choices. Electronics has given tremendous growth in Computer Science, Communication, Control, Instrumentation and Information Technology, . Although electronic devices such as Computer, Cellular Phones and Television are well known, but the insides of these devices are a mystery. Electronics engineering is the knowledge related with the functioning of such electronic devices. The concept electronics is used for electronic components, integrated circuits, and electrical systems. Main areas of usage are modern information technology and telecommunications, tools for recording and playing sound and picture, sensors and steering systems, instrumentation and measurement devices.

This book, designed for the benefit of both graduate and postgraduate students in physics, is a referral which aims to equip them with the most up-to-date information in Electrical Technology and Electronics.
