Kostromitsky A. Development of methods of parametric syntheses and schematics frequency - selective devices of telecommunication facilities

3. Object - the parametric syntheses of transmission functions of frequency-selective devices with difficult characteristics and their practical realization; the aim - the development of the parametric synthesis method on the base of the identification approaches, which allows to make the transition from mathematical to technological model, the realization aspect obviously follows; the development of the recommendations on practical realization the received models; methods – the theory of the identification and the optimization, the spectral and the topological analysis, the simulation modeling on the PC, full-scale experiments; results - software of automation of designing of the frequency - selective devices with the difficult characteristics have been developed; a series of measures in effective practical realization of the technological models including bank base schematics of the solutions are developed; novelty - the specific criterions motivated; for the first time the effectiveness of using multinomial rejection of the filter with the asymmetric frequent characteristic is found and proved and the corresponding scheme is analyzed; for the first time the way of frequent scaling the parameters discrete - analog microcircuit on switched capacitors is developed; the way of identification the order and parameters of the frequent model of the communication channel based on the developed method is offered; application - the received results are used in educational process, during the course work of the s/b research activity and in the industrial activity; branch - the circuitry devices of radio engineering and means of telecommunications
