Advantages of Digital Transmission

Advantages of Digital Transmission
-      noise immunity
o    pulses are evaluated during a precise time interval and a simple determination is made whether the pulse is above or below a prescribed reference level
-      better suited than analog signals for processing and combining using a technique called multiplexing
-      more resistant than analog systems to additive noise because they use signal regeneration rather than signal amplification
-      simpler to measure and evaluate
