Description

низкочастотную составл ющие, отличающийс  тем что, с целью повышени  точности определени , задерживают высокочастотную составл ющую на интервал времени, пропорциональный частоте основной гармоники низкочастотной составл ющей, и наход т коэффициент коррел ции между задержанным и пр мым высокочастотным сигналом.a low frequency component, characterized in that, in order to improve the accuracy of the determination, the high frequency component is delayed by an interval of time proportional to the fundamental frequency of the low frequency component, and the correlation coefficient between the delayed and the direct high frequency signal is found.
