Instead of Circuit Theory, gain equations are extracted from a Signal Flow Graph (SFG) by Mason’s Gain Formula. Voltage Signal Analysis (VSA) creates a SFG from the Circuit Schematic.

Signal flow graph When parallel impedances combine, the parallel combination has a lower value than an individual impedance. If you visualize the circuit as a potential divider, then the signal ...

A signal flow graph is a graphical representation of a system derived from a set of linear equations. 2 An SFG provides a bridge from a transfer function to a corresponding circuit topology of a ...
