Be aware that there might be some kind of delay in signal decoding, think you could get a transfer function for this, if signal is 10kHz I would guess at least one full period is needed to track signal with good accuracy. Analog devices have some with 16 bit resolution per turn, expensive for an integrated circuit but maybe not compared to machine guess it depend on accuracy of machine.
