ConclusionsThus, in the course of a conducted research practical suggestions regarding the implementation of the hardwaredevices forming discrete sequences have been developed.The designed schemes are implemented computationally by efficient converters, for example, based o n circuits with ashift register and an adder (see Fig. 4 – 7). They allow creating large assemblies of discrete signals with improved correlationand assembly properties. Therefore, the developed proposals let to practically implement the developed method of formingdiscrete signals.||Issn <strong>2250</strong>-<strong>3005</strong>(online)|| ||December||2012|| Page 243
