Annotations languages:

The task of determining the amount and face values of frequencies of difficult signals is examined, which differs from the methods of decision of the systems of linear algebraic equalizations known by the use. For the increase of exactness of decision of equalizations in the conditions when an analyzable signal has small duration, the use of transformation of weighing is offered.
