Synchronization of the Demodulator Output
Debouncing of the Demodulator Output
The data from the ASK/FSK demodulator (Dem_out) is digitally processed in different ways and
as a result converted into the output signal data. This processing depends on the selected baud-
rate range (BR_Range).

The minimum time period between two edges of the data signal is limited to t
implies an efficient suppression of spikes at the DATA output. At the same time it limits the max-
imum frequency of edges at DATA. This eases the interrupt handling of a connected
microcontroller.
The maximum time period for DATA to stay Low is limited to T
