With the standard G305 receiver, the FMW mode
button is disabled and the wide FM demodulation mode is not available. This is
because wide FM demodulation is not possible to be provided as part of the G305
software-defined radio system, within the constraints imposed by the processing
power of a standard personal computer.
However, wide-band FM demodulation capability is available as
a factory-installed option. This is in fact a self-contained "hardware-defined"
receiver which shares only the main receiver's front-end and first mixer, but
has an independent wide-band analog processing circuit with a conventional
"hardwired" demodulator.
If the Wide FM Option is installed, the FMW button
becomes active. The demodulator spectrum display shows real-time spectrum of the
demodulated audio. In the Professional Demodulator there is a user-definable
audio filter, displayed superimposed over the audio spectrum and graphically
adjustable.
The Wide-FM Option provides a separate wide-FM
demodulator. The wide-FM demodulation is performed in hardware, using
conventional hardware-based demodulation techniques, in order to ease the
requirement of PC processing power which would otherwise be required for a
signal of this bandwidth. In other words, the Wide-FM Option is an
entirely separate receiver on its own right.
