(DC)

In the history of electronics, first came the analog systems and then the digital systems. However, this is not true for communication systems. It was Samuel Morse (1837) who first demonstrated digital transmission by converting message signal into digital code. The next communication system was an analog system. by Alexander Graham Bell in 1876 In the present day, the digital communication industry is an enormous and rapidly growing industry, roughly comparable in size to the computer industry. Digital communication systems have now become the basic enablers of the information age. Examples include telephone transmission systems, wireless systems, optical transmission systems, digital television etc. This basic course introduces the fundamental principles and concepts dealing with digital communications.
