ECEN 2260 - Circuits/Electronics 2
Required - 5 credit hours
On-Line Course Materials
Prerequisites: APPM 2360, Linear Algebra/Differential Equations and ECEN 2250, Circuits/Electronics 1
Textbook: Thomas and Rosa, The Analysis and Design of Linear Circuits, 4th Ed., Wiley, 2003
Course objectives: ECEN 2260 introduces the student to signal processing circuits and systems including frequency domain analysis and second-order system response in the time and frequency domains. It reinforces these concepts via in-depth laboratory experiments and a short design project. It also assists in the development of problem-solving abilities, including physical thinking, approximation techniques, and design-oriented analysis.
Topics Covered:
- Review: Complex variables, phasor analysis, circuit analysis
- Laplace Transform: Transforms of waveforms, properties, inverse transforms via partial fraction expansion, pole location vs. nature of response
- Circuit analysis in s-domain: Transformed circuits, handling initial conditions, transfer functions, applications of superposition, second-order circuit examples
- Frequency response and Bode diagrams: Filter circuits, magnitude and phase asymptotes, resonant circuits, Butterworth and Chebyshev filters
- Block diagrams: Modeling systems via block diagrams, rules for simplifying
- Fourier series: Rectangular, polar, and exponential forms. Waveform symmetries. Effect of filters on waveform spectra. Complex power and rms values vs. Fourier series
- Introduction to feedback: Op amp feedback examples, effect of feedback on transfer functions and gain/bandwidth, intro to stability
- Exams and review for exams
- Develop design and project skills
- Lab includes a multi-week open-ended design project at end of courseLearn to identify, formulate, and solve engineering problems in a circuits/systems context
- Multi-week assignments involving analysis and modification of circuits having multiple blocks. Students apply theory from course to circuits and systems that do interesting things
- Learn laboratory skills, modern hardware, and tools
- Simulation and measurement of circuits and systems
- Analysis and interpretation of data
- Frequency and transient response measurements
- Writing skills
- Written lab reports and prelab assignments
- Voltage-controlled oscillator (2 weeks)
- Transient response of a second-order system (2 weeks)
- Measurement of transfer functions and impedance (3 weeks)
- Design, construction, and testing of a Butterworth filter (3 weeks)
- Color organ design project (4 weeks)
Contribution of course to meeting the professional component: Contributes 5 semester hours to criterion 4(b) “one and one-half years of engineering topics, consisting of engineering sciences and engineering design appropriate to the student's field of study.”
