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
