Kvitek E.V., Kutuzov V.I., Shevelenko V.D. INCREASE OF SPEED OF INFORMATION HARMONICS PARAMETERS DETERMINATION BY THE METHOD FURIE OF GROUP TRANSFORMATION Expressions for corresponding group signals, allowing to change the character of transformations in the process of realization of the direct return Furie transformations, which allowes to decrease frequency of discretization in comparison with Nayquist frequency for ranges of lower and middle frequencies, are given on the base of signals presentation as a group of frequency components, amassed in the are of lower frequencies, higher and middle friquencies. It allows to reduce number of calculating processes in comparison with needed on the base of quick Furie transformation.
