Abstract
A resolver to digital converter wherein the data from the resolver is processed according to octants which provide the most significant three bits indicating shaft position. The sine and cosine values from the resolver are further processed according to the octant with the smaller value being divided by the larger value to derive a tangent value in the range of zero to one. A look up table can then be used to provide a linear position indication from the tangent values which are then added to the octant value to obtain the shaft position indication.
