Depends on the sensor, but -- maybe. Long and intense conversations with
the sensor vendor are a good idea. With quadrature sensors, the first
thing you want to know is whether the actual physical sensor has as many
lines as the finished sensor is specified for.
Even if the sensor itself is very deterministically measuring the
position of one mechanical bit against another, when your resolution is
very high you can't be sure that there won't be some process (usually
mechanical vibration) that'll look a lot like noise to a Kalman filter.

When you have a digital sensor (say a quad detector for example), how do we estimate the SNR if we are using say a Kalman filter? My own guess is that it will be more or less deterministic baring quantisation noise.
