6. Digital Signal Processing
The data from the ASK 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 baudrate
range (BR_Range).
extended basic clock cycle T
edge-to-edge time period tee_sig of the DATA signal as a result is always an integral multiple of
T
.
XClk
The minimum time period between two edges of the data signal is limited to tee_sig
This implies an efficient suppression of spikes at the DATA output. At the same time it limits the
maximum frequency of edges at DATA. This eases the interrupt handling of a connected
microcontroller.
