detection initiation range
Channel B
- Signal A is normally in quadrature to signal B (90° phase shift).
- A = B = High is the indexed position and is outside of the detection range because of
magnetic indexing.
- The signals should not be evaluated until the state A = B = Low is reached.

UCE.
The pull-up

UCE.
This circuitry protects
the encoder against e.g. surge currents.
