1. A sampling measurement data generation apparatus comprising:

  • means for generating a continuous analog signal which represents a physical state of a moving object to be measured;

    an encoder mechanically coupled to said moving object so as to move in synchronism with the moving object;

    means for generating sampling signals having a period corresponding to movement of said encoder;

    means for generating a measurement start signal and a measurement end signal for presetting a measurement range corresponding to movement of said encoder;

    means for sampling said continuous analog signal using said generated sampling signals;

    means for generating clock signals;

    means for counting the number of said clock signals which appear between each of adjacent two of said sampling signals generated by said sampling signals generation means;

    means for converting said sampled analog signal into digitial signals; and

    means for storing said digital signals;

    whereby the sampling period is determined by the output of said means for counting with said number of said clock signals being related to said digital data stored in said storing means.
