Δ = 1 – Σ loop gains + Σ pairs of non-touching loop gains + extra terms for sets of 3 or more non-touching loops. Δ contains all the loops in the circuit. A loop only affects a path if it touches the ...

Circuit components that connect to ground do not create branches in the SFG. They do affect branch gains via the node Impedance. The SFG is a more intuitive circuit description. To use Mason's gain ...

When it comes to electrical circuits, there’s a lot to remember and understand. We've got you covered with this Intro to Circuits BBC Bitesize guide.
