The task of determination of quantity and face values of frequencies of difficult signals is considered, different from the known by the use methods of decision of the systems of linear algebraic equalizations. It is offered to use the index of diagonal predominance for a priori determination of the required size of informative digital selections of multifrequency signals for the high-quality decision of task of their authentication with the use of methods of linear algebra.
