Lesson 20: Analog to Digital Conversion
www.usna.eduIn a digital communication system, a digital signal is received (receiver decides 0s or 1s), regenerated (digital signal recreated based on the 0s and 1s), and then retransmitted at each station. With signal regeneration, the noise can be eliminated at each station. This can only be done in digital communication systems.
