FIELD: measuring equipment.
SUBSTANCE: method of fixing the intersection or touching the time axis of the observed signal is to generate a first auxiliary signal parallel to the time axis and spaced a small distance from it, and divide mentioned auxiliary signal into an observed signal. The second auxiliary signal resulting from the division consists of needlelike pulses of short duration, the appearance of which uniquely identifies the instants of time when the observed signal vanishes.
EFFECT: possibility of accurately detecting the moments of time when the observed signal vanishes or touches the time axis.
