Использование: изобретение относится к измерительной технике и предназначено для контроля нелинейности различных блоков. Цель: повышение точности измерений. Сущность изобретения: проводят сравнение исследуемого сигнала с образцовым синусоидальным сигналом, при этом в определенные моменты времени to для различных фазовых сдвигов Fo между этими сигналами определяют модули отношений мгновенных значений двух сигналов, усредняют полученные значения, определяют максимальное абсолютное отклонение полученных модулей отношений от их усредненного значения, по которому и определяют нелинейность, превышающую допустимую величину. Положительный эффект: способ имеет существенные преимущества на инфранизких частотах, так как не требует изменения амплитуды образцового генератора, не требует фильтров, но при этом обеспечивается высокое быстродействие, высокая точность измерения и простота конструкции.Usage: the invention relates to a measuring technique and is intended to control the nonlinearity of various blocks. Goal: increase the accuracy of measurements. The essence of the invention: conduct a comparison of the signal under study with an exemplary sinusoidal signal, while at certain times t o for different phase shifts Fo between these signals determine the modules of the ratios of the instantaneous values of two signals, average the obtained values, determine the maximum absolute deviation of the resulting modules of ratios from their average values, which determine the nonlinearity that exceeds the permissible value. Positive effect: the method has significant advantages at infra-low frequencies, since it does not require a change in the amplitude of the reference generator, does not require filters, but at the same time provides high speed, high measurement accuracy and simplicity of design.
