| has gloss | eng: The asymptotic gain model (also known as the Rosenstark method ) is a representation of the gain of negative feedback amplifiers given by the asymptotic gain relation: :G = G_\infty} \left( \fracT}T + 1} \right) + G_0 \left( \frac1}T + 1} \right) \ , where T is the return ratio with the input source disabled (equal to the negative of the loop gain in the case of a single-loop system composed of unilateral blocks), G∞ is the asymptotic gain and G_0 is the direct transmission term. This form for the gain can provide intuitive insight into the circuit and often is easier to derive than a direct attack on the gain. |
