Demodulators
7.8.1
Supported demodulation
Refer to [AD4] for the complete list of available demodulator.
7.8.2
FM discrimator gain adjustment.
The FM discriminator gain depends on the IF filter bandwidth.
In the following example, the simultaneous subcarrier mode has been selected:
Main channel features
IF filter 13 MHz
-
-
Main PCM
In the picture here after, the FM discriminator gain of the demodulator n°3 has been set to nominal. The
IF filter bandwidth is 13 MHz, but as the main channel FM bandwidth is only1 MHz, the signal level at
the bit sync input is very low.
