As an introductory course to circuit design, we begin with fundamental theory of circuit analysis, including lumped time-invariant models of resistors, capacitors, inductors, Ohm's Law, Kirchoff's Laws, nodal and mesh analysis techniques, two-port equivalent circuits, and steady-state AC circuits. The applications of basic circuit analysis techniques in biomedical instrumentation and biological circuitry will be discussed throughout the entire class. In the final part of the course, the principles of cell electrophysiology, bio-potentials and electrical interactions with tissue will be studied. Not for credit in addition to ESE 271.
