The article describes the modification of design method, based on parallel decomposition of dynamic systems described by transfer function. This method is suitable for the development of digital control and signal processing systems with higher accuracy and speed characteristics by parallelizing the computation process. The authors give the program algorhytms that allow the automatic conversion for description of the dynamical system in the form of a transfer function or zero-pole-gain to the sum of first and second order transfer functions. A validation of the described method is made by creating and simulating elliptic filter of order 9 in LabVIEW development system. Analysis of the efficiency and accuracy of the method of decomposition in the time and frequency domain is performed. It is shown that the proposed implementation of a digital filter is equivalent to the classical implementation, and is suitable for solving the current problems of digital signal processing.
