NOTICE
The signal tracks Cos and Sin must be generated independently. This
means that the sine and cosine signals in the encoder must be conducted in
independent channels, from the optics to the interface.
The two signal tracks must not be generated by a common processor.
One signal may not be derived from the other signal via an electronic circuit.
