The sum/difference mode can be used together with the
quasi-peak detector to determine the sound material
mode. If the difference signal on channel B (right) is near
to zero, and the sum signal on channel A (left) is high,
theincomingaudiosignalismono. Ifthereisasignificant
level on the difference signal, the incoming audio is ste-
reo.

FortheHighDeviationMode, theFMprescalingvalues
can be used in the range between 13 to 30 . Please
consider the internal reduction of 6 dB for this mode. The
FIR-bandwidth should be selected to 500 kHz.

Given deviations will result in internal digital full scale
signals. Appropriate clipping headroom has to be set by
the customer. This can be done by decreasing the listed
values by a specific factor.
