There is a schematic in this thread for NG: 3 way link, labeled sin, cos and com. That to me points to a resolver, which is really like a synchro but with two poles at 90 deg instead of 3 at 120.
Basically analog, AC, fixed freq, varying amplitude, going from maxAOA (vmax, 0) to minAOA (0, vmax) and being centered in (0.707vmax, 0.707vmax).
I'm not sure, though.
