The basic making error+s of result of measurements are analyzed at use of methods of exemplary signals and return interpolational models, the problem of optimum sampling of values of exemplary magnitudes is solved.raise of accuracy of measurementserror of measurementsa measuring channelan interpolational polynomialmethods of exemplary signalsповышение точности измеренийпогрешность измеренийизмерительный каналинтерполяционный полиномметоды образцовых сигналов[Купер В.Я., Рубцов М.Г.
