EE 201 - Circuit Theory I

This course is the first course in EE curriculum offered in 2nd year 1st semester. This course aims to introduce the mathematical models for circuit components and then use these models in the circuit analysis. (This course is accompanied with a separate laboratory course (EE213) where the theory introduced in this course is put into practice.)

In the first part of the course, the component classifications (such as memoryless, dynamic, active-passive, linear, non-linear, time-invariant, time-varying) and conservation laws in relation with circuit analysis (energy and charge conservation) are given. The (i,v)  characteristic for 1-port components are introduced. Then, classical circuit analysis methods are examined on linear resistive circuits. Network theorems (Thevenin-Norton equivalents and Tellegen’s Theorem) are given. Then, the effect of non-linear components are introduced via a brief study of small signal analysis and circuits with piecewise linear components (ideal diodes) are studied. Resistive 2-port descriptions are studied. Op-amp models and their usage in the analysis is studied.  After the introduction of dynamic components, the course concludes with the 1st and 2nd order circuits. The zero-state/zero-input decompositions are given. The constant coefficient differential equations (CCDE) and their solutions (homogenous and particular solutions) are underlined and put in relation with circuit analysis. The impulse, step-response and other response are studied. The dynamic circuits with switches (linear time-varying circuits) and ideal diodes (dynamic circuits with non-linear components) are studied.

The topics of this course and the following course (EE202) builds a foundation to several sub-fields of electrical and electronics engineering. Several topics introduced in these courses are studied in much more depth in some specialized courses.
