Transformation: Transfer Function ↔ Signal Flow Graph

Example: Transfer Function → Signal Flow Graph

Find a signal flow graph for the system described by the transfer function:

Step 1: Find a state space representation using the methods described here (TF ↔ SS).  In this case we are using a CCF form).

Step 2: Find a signal flow graph using the methods described here (TF ↔ SFG).

Example: Signal Flow Graph→ Transfer Function

Repeat the previous example, but reverse the order (i.e., do step 2 (SFG → SS) then step 1 (SS → TF)).

A better way do this is to use Mason's gain formula.
