A method of analog-to-digital conversion of physical values and ratios thereof, consisting in that the value to be digitized is compared against a reference scale of standards based on the value of a divisor, and then several complementary scales are successively compared against the reference scale, each of the complementary scales being shifted relative to the reference scale by a value equal to the remainder left over as a result of the preceding comparison, the number of comparison operations being selected in accordance with the required accuracy of conversion, while the standards of the reference scale are presented in the course of each comparison as a sum of a coincidence zone equalling the required error of the sampling constant during the given comparison and a non-coincidence zone equal in magnitude to a respective complementary scale; and devices based on said method for analog-to-digital conversion of frequency-time signals (time intervals, duration of electric pulses, frequency of oscillations, phase shift angle between two oscillations, etc.). |
