A
passive
network
comprising
usually,
but not
always,
resistors
that
reduces
the
power or
voltage
level of
a signal
without
introducing
significant
distortion.
A
potentiometer
(pot)
that is
used to
lower
the
amplitude
of the
signal
passing
through
it. The
amplitude
can
usually
be set
to any
value
between
full (no
attenuation)
and zero
(infinite
attenuation).
Pots can
be
either
rotary
or
linear
(sliders),
and can
be
either
hardware
or
"virtual
sliders"
on a
computer
screen.
The
attenuator
is used
to
attenuate
a
received
signal.
Reduction
varys
between
models
and is
measured
in
decibels.
Why
would
someone
want to
use
this? It
is
usually
used to
reduce
interference
from
intermodulation. |
