There are a few forms of digital
communication modulation techniques
applicable to the RCS endorsement.
Since we are talking digital, we are
talking about two states, zero and
one. Two forms of digital modulation
techniques are Phase Shift Keying and
Frequency Shift Keying.

In the PSK system, the transmitter
sends a continuous carrier, which
shifts phase with each change
between zero and one. PSK is easy
to understand when you see the
decoding process, which is illustrated
in Figure 3. Typically, a PSK signal
will start with no data, which allows
the receiver to synchronize an internal
signal with the incoming signal.
The phase shifting frequency is then
compared with the internal reference
frequency. They algebraically add,
which yields a signal that in places
is double amplitude and is absent
in others. This added signal can
be rectified, or more specifically
detected, into zeros and ones.
In the FSK system, the transmitter
also sends a continuous carrier;
however, in this case, the frequency of
the carrier changes. In these receivers,
filters can be used to discriminate
between the two frequencies.
The output of one filter would be
designated as a digital zero, where
the output of the other filter would
be designated as a digital one. Figure
4 shows a frequency shifted signal,
along with a block of a possible
detector.
There are countless variations
of these methods of modulation.
Fortunately for those studying for
the RCS endorsement, as of this
writing, only four are covered in the
exam. Those studying for the RCS
endorsement should also research
multiple access systems. Next month,
we will discuss how to get these
signals out of the radio, into space,
and vice versa. q
