Abstract The simple digital filters are not sufficient for digital modeling of systems with distributed parameters. It is necessary to apply more complex digital filters. In this work, a set of filters, called the digital function filters, is proposed. It consists of digital filters, which are obtained from causal and stable filters through some function transformation. In this paper, for several basic functions: exponential, logarithm, square root and the real power of input filter, the recursive algorithms of the digital function filters have been determined The digital function filters of exponential type can be obtained from direct recursive formulas. Whereas, the other function filters, such as the logarithm, the square root and the real power, require using the implicit recursive formulas. Some applications of the digital function filters for the analysis and synthesis of systems with lumped and distributed parameters (a long line, phase shifters, infinite ladder circuits) are given as well.

The article is devoted to the analysis of the role of the Northern Sea Route (NSR) in the socio-economic development of the Arctic zone of Russia. The authors believe that climate change, gradually leading to the melting of polar ice, opens up new opportunities for the development of Arctic resources and navigation in the seas of the Arctic Ocean. Of particular interest to the NSR are non-Arctic countries, critically dependent on the supply of foreign mineral and carbon resources, as well as on the export of their goods to Europe. Among them, China stands out, considering the NSR as the Arctic Blue Economic Corridor as part of the global Silk Road system. The NSR is intended to become an essential tool for further development of the Arctic zone of Russia. Development of port infrastructure and creation of a modern ocean and maritime fleet will accelerate the pace of socio-economic development of this strategically important region. To do this, it is necessary to adopt a federal law on special system of preferences for investors, including foreign ones, implementing their projects in the Arctic. Among such preferences there are preferential profit tax rates, reduction in Mineral Extraction Tax (MET) rates, a declarative procedure for VAT refunds, a simplified procedure for granting land plots and unchanged conditions for the implementation of investment projects. In addition, it is important to make the NSR safe and profitable both in terms of quality of service and of price for the shippers. In particular, the payment for icebreakers’ escort of vessels should be competitive and reasonable. The largest Russian private and state-owned companies should be involved into Arctic projects. It is important to synchronize the Arctic oil and gas projects with nuclear and LNG icebreakers’ construction, as well as with the launch of two logistics hubs in Murmansk and Kamchatka. In this case, year-round NSR navigation will be organized, which will ensure the high competitiveness of Russian products supplied to the Asian Pacific markets.
