Principles+of+digital+communication - 资源详细说明
Communication has been one of the deepest needs of the human race throughout recorded
history. It is essential to forming social unions, to educating the young, and to expressing a
myriad of emotions and needs. Good communication is central to a civilized society.
The various communication disciplines in engineering have the purpose of providing technological
aids to human communication. One could view the smoke signals and drum rolls of primitive
societies as being technological aids to communication, but communication technology as we
view it today became important with telegraphy, then telephony, then video, then computer
communication, and today the amazing mixture of all of these in inexpensive, small portable
devices.
