Introduction to communication technology

Communication technology, also known as communication engineering (and information engineering, telecommunications engineering, old say telecommunication engineering, weak current engineering) is an important branch of electronic engineering, is also one of the basic subjects. This discipline focuses on the principles and applications of information transmission and signal processing in communication. Communication engineering studies the transmission of information, in the form of electromagnetic waves, sound waves, or light waves, through an electric pulse, from the sending end (source) to one or more receiving end (host). Whether the receiver can recognize the information correctly depends on the loss power in transmission. Signal processing is an important link in communication engineering, including filtering, coding and decoding. Major courses include computer network principle, circuit, communication system, exchange technology, wireless technology, computer network, communication electronic circuit, digital electronic technology, optical fiber communication, etc.
