Resolvers and Synchros are transducers that convert the angular position and/or velocity of a rotating shaft to an electrical signal. Both deliver signals proportional to the Sine and/or Cosine of the shaft angle. A Resolver-to-Digital or a Synchro-to-Digital converter is used to convert these signals to a digital output corresponding to the shaft angle and/or velocity. ADI’s family of RDCs and SDCs offers solutions for these applications.
