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:
“The historian must have ... some conception of how men who are not historians behave. Otherwise he will move in a world of the dead. He can only gain that conception through personal experience, and he can only use his personal experiences when he is a genius.”
—E.M. (Edward Morgan)
“I’d like to be the first model who becomes a woman.”
