Noise Detector:
To decide whether there is a data signal or simply noise at the output of the demodulator,
there is a noise detector implemented. The principle is based on a power measurement
of the demodulated signal. The current noise power is stored in the FSKNP register and
is updated at every SPI controller access.
The Noise Detector is useful if data signal is transmitted with small FSK deviations.
Further information about the use of the Noise Detector is found in
Filter and Signal
2.4.11
The Clock Recovery uses the peak from the matched filter as reference and generates
the recovered clock. The second main functionality is the generation of the symbol
synchronization found indication. This generally happens within the first 4 bits.
