For the adequate description of digital filters with arbitrary structure it is convenient to use so-called topological matrixes. Elements of these matrixes are transmission coefficients between corresponding nodes of the block diagram. Methods of the analysis of power of round-off noise in the digital filters, based on state-space representation of digital filters are known. In this paper the technique of analysis of round-off noise in the IIR digital filter with any structure described by its topological matrix is offered.
