Demodulator Structure
The G3 SERIES Professional Demodulator implements the general
quadrature representation of all narrow-band modulated signals. Such
signals can always be considered as the sum of two amplitude-modulated
carriers
having a 90 degree offset, usually referred to as
I
and
Q
. Users familiar with
Software Defined Radio
digital signal processing concepts, will find the G3
SERIES Professional Demodulator to be a useful tool for experimentation
and study, where the effects of various filter settings can be easily observed
and optimized.
AM Demodulator Structure
The demodulator structure windows include two spectrum analyzers making
it possible to view signal spectra in real-time. Each analyzer can be
"connected" to any of the
test points
shown as green dots in the diagram. To
