If you recognize feedback, you (not I) may be able to collapse the feedback loop. This can work if you know the tricks. VSA creates Signal Flow Graphs (SFG) and applies Mason’s Rule also known as ...

You will need complex arithmetic to evaluate a gain equation, but not in the formula derivation A simple way to create a gain equations is via a Signal Flow Graph (SFG ... The example SFG has a loop ...
