Asymptotic Gain Model
In the above analysis the feedback network is unilateral. However, real feedback networks often exhibit feed forward as well, that is, they feed a small portion of the input to the output, degrading performance of the feedback amplifier. A more general way to model negative feedback amplifiers including this effect is with the asymptotic gain model.

Famous quotes containing the words gain and/or model:
“We go to gain a little patch of ground
That hath in it no profit but the name.”
—William Shakespeare (1564–1616)
“When Titian was mixing brown madder,
His model was posed up a ladder.
