When analyzing and synthesizing digital filters with different structures, their representation in the state space is most often used. But this is not the only way to describe the filter. A digital filter with an arbitrary structure is most adequately described by a topological matrix, the elements of which are transfer coefficients between nodes of a block diagram. This paper allows us to expand the capabilities of the mathematical model of a digital filter in the form of a topological matrix.
