Abstract: A numerical control system is provided for a table having a relatively stationary member, a relatively movable member and a position transducer, such as an inductosyn, operatively positioned between them. The numerical control system comprises a high frequency clock which generates a pair of sinusoidal waves to the inductosyn at a lower frequency and the phase of the output signal from the inductosyn is representative of the position of the movable and stationary members. A direction and speed control circuit generates an output signal the frequency and polarity of which is indicative of the desired speed and direction of movement of the movable member, respectively, and this output signal is combined with the high frequency signal from the clock by a signal combiner.
