What is signal flow graph in DSP?

A signal flow graph is a network of directed branches that connect at nodes. It is equivalent to block diagrams which we are already familiar with, except for a few notational differences. As examples, OSB Figures 6.8 and 6.9 depict the general form of signal flow graphs.

For which systems are the signal flow graphs applicable?

Linear signal-flow graph (SFG) methods only apply to linear time-invariant systems, as studied by their associated theory.

What are the two basic elements of signal flow graph?

Nodes and branches are the basic elements of signal flow graph.

Why signal flow graph is used?

Signal flow graph is used to find the transfer function between the output and input node.
