description: This paper is devoted to solving the problem of digital signal processing. Modern trunking communication systems in parallel implement the transfer of large amounts of data, so that the reception and formation of signals in these systems require effective methods of filtering, which can provide a high rate of processing and minimal signal distortion. To solve this problem, we analyzed methods of implementation of digital multi-channel filters, including methods of changing the sampling rate and spectrum transfer. Software implementation consisted in the implementation of functional modules: decimators, interpolators, resamplers, filters and other auxiliary modules. The analysis of algorithms computational complexity and the value of calculation error was performed during the development. The presented development can find application in devices for signal reception and processing in trunking communication systems. Open educational resources and information search and analysis programs were used. Used means of automation (automated) development Visual Studio. MATLAB software was used (tested).
