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:
“They had their fortunes to make, everything to gain and nothing to lose. They were schooled in and anxious for debates; forcible in argument; reckless and brilliant. For them it was but a short and natural step from swaying juries in courtroom battles over the ownership of land to swaying constituents in contests for office. For the lawyer, oratory was the escalator that could lift a political candidate to higher ground.”
—Federal Writers Project Of The Wor, U.S. public relief program (1935-1943)
“I had a wonderful job. I worked for a big model agency in Manhattan.... When I got on the subway to go to work, it was like traveling into another world. Oh, the shops were beautiful, we had Bergdorfs, Bendels, Bonwits, DePinna. The women wore hats and gloves. Another world. At home, it was cooking, cleaning, taking care of the kids, going to PTA, Girl Scouts. But when I got into the office, everything was different, I was different.”
—Estelle Shuster (b. c. 1923)
