Representing feedback circuitry as two-port networks
I'm taking an electrical engineering course and we are covering the effect of feedback on the bahaviour of amplifiers. … I learnt the 4 basic topologies, and how with each configuration the feedback circuit can be replaced with a two-port network. …
