Op-amps, worked in 3D.

ECE 3355 Homework 5, every printed problem. Each circuit is rebuilt in 3D from the homework figure; turn it, and step through a solution that starts from the symbols and only then puts in numbers. Reactive circuits come with exact and straight-line Bode plots and a pole-zero map.

              Dots and arrows show conventional current (+ to −). An ideal op amp draws no input current, so its input leads never carry dots. A filled ring is an input driven by a source referenced to ground; values appear next to it.
