Some amount of incident signal ... flow will always enter the loop. The loop may be removed, and its effect applied to that entering path as follows (Fig. 5). 4. According to the self-loop rule ...

This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the schematic. Just find a ...

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 ... gain formula we need to find ...
