The research object is the process of correction of the dynamic errors of the results of the analog-to-digital signal conversion in the high frequency band. The research purpose is increasing of the resolution of the analog-to-digital conversion devices using correction of the dynamic errors, which appear in conversion high frequency signals in the computer systems. Methods are based on usage: theory of the analog-to-digital conversion, signals theory, theory of the random processes, theory of the error, theory of the digital signal processing, heuristic synthesis, computer simulation. Theoretical results - the method of correction of the dynamic ADC errors, which in contrast to known provides correction of the results of analog-to-digital conversion in the phase plane, and both the inertia of the ADC and the rate of the input signal are taken into account each quantization step, is suggested. The method of the correction of the linearity error of the ADC under conversion of the high frequency signals, which is in contrast to existing based on estimation of the distortion of the distribution function of the input test signal under the calibration, is suggested. The analytic formulas for the estimation of the effective number of bits and the ADC quality factor are given. The analytic formulas for estimation the losses of the effective number of bits from the differential nonlinearity and normalized dynamic error.
