Description

The invention relates to oolasts (p; itel (H: OW technicians and washes) to be used with their own me (re1I | Stati ST Ichvs. X, characteristic of TeipwcTiHiK fluctuations of the phase of the antnal.

Ivvstviln izalizatyur. Of repulsive phase units, used in:

In the star analyzer, the low spot has a low TO4iHiO (CTb measurement of fluctuations of the phase of signals due to the large log resolution of TJ) (T), the emerging Lree operationist;

The purpose of the invention is to increase the accuracy of measurements.
