EE 3001B - Signals and Circuits I

3 lecture hours 2 lab hours 4 credits

Course Description
The theory and circuit applications of periodic signals are covered in this bridge course. The power in a circuit with multiple frequencies is investigated initially. Periodic signals are analyzed in circuits and filters using the sine and cosine forms of the Fourier series. The spectra of periodic signals are constructed from the Fourier series and signal distortion types are identified. The course concludes with the analysis and development of operational amplifier circuit relations. Laboratory experiments will reinforce the concepts presented. Note: This course is intended for transfer students and should be taken only upon approval of an EE program advisor. (prereq: full admission into the AAS-EET to BSEE transfer track or consent of an EE program advisor)
