EECS 314: Electrical Circuits, Systems, and Applications

Instructor: Professor Alexander Ganago

EECS 314 Electric circuits, Systems, and Applications covers topics in electric circuits, electronics, and control systems for non-EE majors.

In EECS 314 you will:
• Learn the concepts and principles of Electrical Engineering (EE), which are at the heart of today's analog and digital electronic devices
• Understand, build, and analyze electronic circuits such as amplifiers, filters, temperature controller, etc.
• Learn the language of EE colleagues, which will enable you to work effectively in multi-disciplinary teams.

Engineering is a practical profession; new learning becomes valuable when you apply it to building things: this is what you do in the lab. EECS 314 Labs include computer-controlled experiments based on LabVIEW - software very popular in industry; experience in using it may be advantageous for your job search. The new Temperature Controller Lab introduces you to Analog/Digital, and Programmable circuits - examples of Embedded Systems widely used in industry as well as consumer electronic devices.

Contents of EECS 314 Labs:
1) DC Lab
• Measure voltages, currents, and resistances; learn to avoid blunders
• Prove that a Light-Emitting Diode (LED) does not obey Ohm's law
• Learn that a MOSFET transistor act as an electronic switch
2) AC Lab
• Measure the Rise and Fall Time of standard signals; compare with theory
• Measure FFT spectra of standard signals; build various waveforms of sine waves
• Measure Telephone tone dialer signals - waveforms and FFT spectra
3) Transients Lab
• Study exponential responses of RC circuits to square wave input signals
• How many pulses does you system receive when 2 pulses are sent?
• Measure 3 types of responses of RLC circuits to square wave input signals
4) Filters Lab
• Solder your own circuit, which acts as any of the 4 types of filters
• Measure the transfer functions of each type of filter, using your circuit
• Observe and study resonance in your circuit
5) Operational Amplifier (Op Amp) Lab
• Build several amplifiers with fixed and variable gain; study their responses
• Build and study an active filter that can amplify and suppress signals
• Turn your circuit into a comparator key block of a control circuit
6) Analog/Digital, and Programmable Temperature Controller Lab
• Verify the functionality of two temperature controllers
• Measure the voltages and determine the logic states in A/D controller
• Change the functionality of Programmable controller by altering the C code
