The
purely
sinusoidal
component
of a
complex
waveform
that
carries
a signal
from a
transmitter
to a
receiver.
The
carrier
wave
itself
cannot
transmit
information
but must
be
changed
or
modulated,
two
common
methods
for
doing so
being
amplitude
modulation
and
frequency
modulation.
A
carrier
wave is
a
waveform
(usually
sinusoidal)
that is
modulated
(modified)
to
represent
the
information
to be
transmitted.
This
carrier
wave is
usually
of much
higher
frequency
than the
modulating
signal
(the
signal
which
contains
the
information).
