In the present work classification of variants of an interference is resulted and
conditions are analyzed, at which addition of signals probably without rejection or a addition of energy from the outside. It is shown, that at decomposition of signals there is no equality of density of energy and balance of energy is carried out only on final intervals.
On the basis of the analysis of threshold and limiting density of energy the
estimation of information throughput of electromagnetic signals in space is carried out.
