Audio degradation due to
weak reception
In a digital wireless system, sound quality is
maintained up to the maximum
transmission range. Beyond this point, as
the radio wave becomes weaker, data
synchronization is lost and the connection
finally breaks. Sony digital wireless
systems suppress the occurrence of large
noise between these two points as the signal
weakens. As a result, digital processing is
conducted in a way that allows the signal to
degrade in a very natural way.
