Implementation
Of
Modulation
Techniques
on SpinCore PulseBlasterDDS
and RadioProcessor Boards
Introduction
SpinCore's
PulseBlasterDDS and RadioProcessor boards can be
used to perform a
variety of signal modulation techniques. Signal
modulation allows for
one signal to be transmitted using another
signal. This procedure is
useful because some signals cannot physically be
transferred over
certain media. The original signal is
referred to as the
modulating signal, and the signal that it is
packed inside of is
referred to as the carrier. Signal modulation is
used for everyday
applications such as FM & AM radio, ethernet
communications, and
HDTV.
These
pages show how to implement a wide variety of
signal modulation
techniques on PulseBlasterDDS and
RadioProcessor boards. They also show
the
use of these boards to generate carriers of
various shapes that could
be
used in NMR experiments.
The modulation techniques
are further explained in the sections given
below. For more details, please click on the
