Abstract. The conditions of increasing the accuracy of digital measurement of repeating signal parameters (increasing the resolution) in measuring radio reception systems by reducing sampling and quantization errors, with a random nature of the change in the measurement conditions (experiment conditions) are analyzed. The method of reducing the errors of digital measurement during random modulation of the phase of the quantizing sequence and conducting multi-stage measurements using recursive optimal estimates from the theory of statistical estimation is analyzed in detail. By analogy with adaptive digital filters, a hypothesis is put forward about the possibility of increasing instrumental accuracy (reducing instrumental errors) in measuring repeated time intervals with random modulation of the initial phase of quantizing pulses and using feedback in the experiment. Thus, the fundamental possibility of creating the fundamental basis of ultra-precise measurements is proved. Similarly, an increase in image sharpness along the X, Y axes is realized, for example, the aperture of the line of receiving sensors and the use of rough ("Boolean") statistics of the input signal. The approach based on the recursion of measurements due to changes in the conditions of the experiment using the statistical test method (Monte Carlo method) is considered. To clarify (interpolate) the position of the end of the measured segment inside the resolution element and thus achieve the effect of “instrumental overresolution” of multiple measurements.
