called systems. The data rate and
bandwidth are often different from one another.
Bandwidth
The bandwidth (B) describes the difference mag-
nitude between the two frequencies either end a
frequency band. The critical point de-
scribed the cut-off frequency fg. case open or
short-circuited end cable, this can result the
doubling cancellation the signal wave. Technically, the “data volume”
is, however, fact the data rate.
Cut-off frequency fg
The cut-off frequency describes the frequency-de-
pendent behaviour the arrestors. The cut-off frequency determined according
to certain measuring criteria.
In data technology the bandwidth often described
as the “data volume”. From this point on-
wards, the signal has lost 50% dB) its input
power.
If there mismatch, e. Standing
waves can occur if, for example, there terminat-
ing impedance the cable, two cables differ-
ent impedances are connected together, for example
a Ohm coaxial cable with Ohm coaxial cable. Capacitive and/or
inductive component properties ensure signal damp-
ing higher frequencies.
