  • An Advanced Steering Wheel Sensor
    different from standard incremental encoders. Electronic multiplication, or interpolation, provides a higher degree of angular resolution while trading off some pattern regularity. While this may not be suitable for velocity servos, it is ideal for position readouts and position sensors. The most
