Abstract

The aim of this work is to present new limits of application of some often applied criteria of evaluating and measurements bandwidths (linewidths) and to compare the results. There were given results of comparison bandwidths calculated for twelve typical signals according to six definitions of bandwidths applied and 12 coefficients for 'informational criterion' of bandwidths. It was demonstrated that the problem of evaluating or measuring bandwidths cannot be solved by applying any definition of bandwidth separately, because there exist some cases for which the antinomies are very strong.
