Course Descriptions

17.213 Circuits I
Discusses: electrical circuits; voltage, current and resistance; energy, power and charge; Ohm’s Law, Kirchhoff’s Current Law and Kirchhoff’s Voltage Law; simplification and conversion techniques for networks containing sources and/or resistance; Thevenin’s and Norton’s theorems; fundamentals of magnetism and magnetic circuits; properties of capacitance and inductance and associated transient behavior of circuits.
Prerequisite: 92.125 (May be taken concurrently), 90.267.
Credits: 3

17.214 Circuits II and Laboratory
Provides a continuation of 17.213. Topics include sinusoidal waveforms, phasors, impedance and network elements. Mesh and nodal analysis of AC circuits; series and parallel circuits, superposition and Wye/Delta conversions are also covered. The use of power supplies and various electrical measuring instruments will be studied. DC circuit analysis concepts studied in 17.213 will be verified by laboratory experiments. Written reports are required. Alternate lecture and laboratory sessions.
Prerequisite: 17.213.
Credits: 2

17.215 Circuits III and Laboratory
Serves as a continuation of 17.214. Topics to be discussed include maximum power transfer, real and reactive power; resonance; and polyphase systems. Oscilloscopes, voltage, current and phase measurements are demonstrated. Other topics include series and parallel sinusoidal circuits, series-parallel sinusoidal circuits, series resonance, parallel resonance and transformers. Filters, 2-port networks, computer aided circuit analysis (SPICE). Computer terminals will be available in the laboratory and their use is expected. Written reports are required. Alternate lecture and laboratory sessions.
Prerequisite: 17.214.
Credits: 2

17.216 Circuits IV
Circuits IV is a continuation of passive circuit analysis, where the student is introduced into the frequency domain. LaPlace techniques are used to analyze electric circuits using sources and elements similar to those in earlier circuit analysis courses. The concept of boundary conditions is introduced along with initial value and final value theorems. There is a brief review of mathematical concepts such as logarithm, exponential functions and partial fraction expansion to aid the student for newer analysis techniques. The S plane is introduced as a graphical technique to plot the poles and zeros of a function and acquire an insight into the time domain. The duals of electrical elements in other engineering fields (mechanical, fluids, and thermal) are introduced and analyzed using LaPlace techniques. Bode plots are used as another tool to gain insight into the time domain. The cascade interconnect is introduced along with the concept of transfer functions and impulse response. Filter circuits are again analyzed but this time in the frequency domain using the concepts of LaPlace and Bode.
Prerequisite: 17.215.
Credits: 3

17.355 Electronics I and Laboratory
This course introduces Electronics from a fundamental perspective and analyses of circuits from a practical point of view. Semiconductor devices and their application are stressed. This course surveys the operating characteristics of pn junction diodes, transistors and operational amplifiers, and analyzes their application in actual circuits. The use of diodes in power switching circuits and the use of transistors in logic circuits and amplifiers will be covered extensively. Examples and homework, based on present-day applications, are designed to provide practice in the use of fundamental concepts and applications. It is expected that following the four-course electronic sequence, students will be able to use the textbook used in this course or other professional level electronic texts for further study of specific electronic topics. The course includes computer applications in solving problems involving models of electronic devices and circuits. Coverage of some topics is based on notes handed out that augments coverage in Sedra and SMith.
Prerequisite: 17.215, 42.226.
Credits: 2

17.356 Electronics II and Laboratory
This course surveys the operating characteristics of bipolar junction transistors (BJTs); circuit symbols; nonlinear, large-signal behavior of BJTs; operational amplifiers and analyses; and their application in actual circuits. Large-signal, piecewise, linear DC BJT circuits and small-signal AC BJTs will be studied. This course covers BJTs as used in amplifiers, switches cutoff, and saturation. P- and N-channel MOSFETs and junction field-effect transistors (FETs) will be introduced and discussed. These include linear, small-signal AC models. Examples and homework, based on present-day applications, are designed to provide practice in the use of fundamental concepts and applications. The course includes computer applications in solving problems involving models of electronic devices and circuits. Coverage of some topics is based on notes handed out, which augment coverage in the text.
Prerequisite: 17.355.
Credits: 2

17.357 Electronics III and Laboratory
This course introduces electronics from a fundamental perspective and analyses of circuits from a practical point of view. It is expected that following the four course electronic sequence, students will be able to use the textbook used in this course or other professional level electronic texts for further study of specific electronic topoics. Differential amplifiers and frequency response of different types of amplifiers will be discussed. After taking this course a student should be able to design and analyze different types of multistage amplifiers. They will be able to know the frequency response of such amplifiers. Examples and homework, based on present day applications, are designed to provide practice in the use of fundamental concepts and applications. The course includes computer applications in solving problems involving models of electronic devices and circuits. Coverage of some topics is based on notes handed out that augments coverage in Sedra and Smith.
