Wireless Communication

There are a variety of wireless communication systems for transmitting voice, video, and data in local or wide areas. There are point-to-point wireless bridges, wireless local area networks, multidirectional wireless cellular systems, and satellite communication systems. This topic discusses "mobile" wireless technologies that provide voice and data communication services to mobile users who use cell phones, PDAs, Internet terminals, and related computing devices. Refer to "Wireless Communications" for a list of related wireless topics. The number of wireless mobile devices is increasing globally. Users equipped with portable computers, PDAs (personal digital assistants), and a variety of small wireless communication devices increasingly need to connect to corporate networks, perform database queries, exchange messages, transfer files, and even participate in collaborative computing. At the same time, wireless systems are achieving higher data rates to support Internet and other data-related applications. The newest mobile communication systems are targeting data rates as high as 2 Mbits/sec.

Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. This field first became an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use. Subsequently, broadcasting and recording media made electronics part of daily life. The invention of the transistor and, subsequently, the integrated circuit brought down the cost of electronics to the point where they can be used in almost any household object. There are some videos are uploaded for the basic knowledge of electrical engineering students which are as below.

1. A.C. Generator Video
2. A.C.Fundamentals
3. Hysteresis Loop
4. How to build an Electric Transformer
5. CRT Video-1

7. Classification of Transformers

Electronics Circuit Video

As Physics is the mother of all engineering disciplines, students must have some basic knowledge on physics to understand their core engineering subjects more comfortably. Accordingly, in reviewing the syllabus, emphasis has been given on the principles, laws, working formula and basic ideas of physics to help them study the core subjects. Complicated derivations have been avoided because applications of the laws and principles of physics are more important for engineering students. Therefore there are some video are uploaded below for clear idea about basic function related to some circuit and component used in electronics circuits. 

1. Full wave bridge rectifier
2. Half and Full wave rectifier
3. Intrinsic And Extrinsic Semi Conductors
4. Types of Semiconductors
5. The PN Junction-How Diodes Work
6. Zener Diode
7. Valence Band, Conduction Band and Forbidden Energy Gap
8. PNP Transistor
9. How to identify PNP and NPN Transistor
10. Zener as Voltage regulator
