Lyubchyk V. Measuring frequency characteristics from radiosignals with rectangular turnline of spectrum.

The thesis is dedicted for eleboration of mathematic models of measuring signals with rectangular turnlineof amplitude-frequency spectrum and eleboration devices for realisation signals with defined charachteristics of amplitude-frequency spectrum. In this work characteristics of methods for measuring of amplitude-frequency charachteristics are perfomed in which basic is inserted by measuring signals that are used. The mathimatic models of orthogonal pair of signals with rectangular turnline of spectrum are eleborated. Their impruvement by, using criterion of minimum in bandwidth is conducted. The spectrum metod of amplitude-frequency measuring with using new signals is used.
