Improvement of Position and Velocity Detecting Accuracy by Signal Perturbation
Eugene S. Mcvey, Pi-Fuay Chen · IEEE Transactions on Industrial Electronics and Control Instrumentation · 1969
A method is presented for increasing the accuracy of position and velocity detecting systems which make use of pattern recognition principles. The basic limitation of these systems is due to the binary nature of receptor elements which causes the receptor to have a nonlinear transfer characteristic.
