The reverse isolation parameter determines the level of feedback from the output of an amplifier to the input and therefore influences its stability (its tendency to refrain from oscillation) together with the forward gain . An amplifier with input and output ports perfectly isolated from each other would have infinite scalar log magnitude isolation or the linear magnitude of would be zero. Such an amplifier is said to be unilateral. Most practical amplifiers though will have some finite isolati… WebGeneral Representation for the Rollett Stability Factor of a Two-Port Network Published in: IEEE Transactions on Circuit Theory ( Volume: 16 , Issue: 2 , May 1969 ) Article #: clothes relief https://thebodyfitproject.com
