Signal flow graph . To construct the SFG we need models for an Impedance Z and an op-amp. Let’s do the easy one first. The op-amp schematic and SFG are shown below. Op amp schematic . Op amp signal ...

Mason’s Gain Formula is the input to output gain formula (transfer function) for any Linear Circuit. To use it, you need a SFG. Instead of Circuit Theory, gain equations are extracted from a Signal ...
