Appendix A: Definitions
Resolution (3 noise level)
Refresh rate
The smallest angle increment distinguishable from the noise. Here the resolution
is defined as 3 times , the standard deviation in degrees, taken over 1000 data
points at a constant position. The resolution in bits is obtained with:
6.
Rate at which new data points are stored in the output buffer.
Latency
The time between the data ready at the output and the instant at which the shaft
passes that position. The lag in degrees is
, where is the
angular velocity in deg/s.
Power up time
Starting at power up, time until the sensor delivers valid data.
Integral Non-Linearity (INL)
Maximum deviation between the sensor output and the best line fit.
