Why Digital Communications
{"Image DocumentName": "Why Digital Communications?", "Image ImageDescription": "Easy to regenerate the distorted signal. Regenerative repeaters along the transmission path can detect a digital signal and retransmit a new, clean (noise free) signal. These repeaters prevent accumulation of noise along the path. This is not possible with analog communication systems. Two-state signal representation. The input to a digital system is in the form of a sequence of bits (binary or M_ary) Immunity to distortion and interference. Digital communication is rugged in the sense that it is more immune to channel noise and distortion.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
