Formula
The gain formula is as follows:
where:
- Δ = the determinant of the graph.
- yin = input-node variable
- yout = output-node variable
- G = complete gain between yin and yout
- N = total number of forward paths between yin and yout
- Gk = gain of the kth forward path between yin and yout
- Li = loop gain of each closed loop in the system
- LiLj = product of the loop gains of any two non-touching loops (no common nodes)
- LiLjLk = product of the loop gains of any three pairwise nontouching loops
- Δk = the cofactor value of Δ for the kth forward path, with the loops touching the kth forward path removed. *

Famous quotes containing the word formula:
“I feel like a white granular mass of amorphous crystals—my formula appears to be isomeric with Spasmotoxin. My aurochloride precipitates into beautiful prismatic needles. My Platinochloride develops octohedron crystals,—with a fine blue florescence. My physiological action is not indifferent. One millionth of a grain injected under the skin of a frog produced instantaneous death accompanied by an orange blossom odor.”
—Lafcadio Hearn (1850–1904)
“Given for one instant an intelligence which could comprehend all the forces by which nature is animated and the respective positions of the beings which compose it, if moreover this intelligence were vast enough to submit these data to analysis, it would embrace in the same formula both the movements of the largest bodies in the universe and those of the lightest atom; to it nothing would be uncertain, and the future as the past would be present to its eyes.”
—Pierre Simon De Laplace (1749–1827)
““It’s hard enough to adjust [to the lack of control] in the beginning,” says a corporate vice president and single mother. “But then you realize that everything keeps changing, so you never regain control. I was just learning to take care of the belly-button stump, when it fell off. I had just learned to make formula really efficiently, when Sarah stopped using it.””
—Anne C. Weisberg (20th century)
