The conversion units and data transfer with frequency data coding are perspective for a reliability raising and transmission accuracy of the information in control systems, communication systems, computer networks etc. One of directions in creation of high-reliable microelectronic components of computer facilities and control systems is the development of multifunction frequency elements on the basis of nonlinear resonant circuits (NRC). The multifunctionality of such elements at their schematic simplicity is determined not by a number of components and complexity of structural organization (as in large integrated circuits), and purposeful usage of numerous effects having a place in nonlinear vibratory circuits. The results, obtained by the authors, gain the significance in modern conditions, when the semiconducting production process of large integrated circuits for microprocessors practically has reached a physical limit of decreasing the sizes of components and width of interconnections. Alternative can be only usage of artificial intelligence systems, the elements of the multivalued logic on the basis NRC can be applied to their construction. Experimental samples of such elements have been realized in the form of thin-film microcircuits in a standard body.
