EE 3002B - Signals and Circuits II

4 lecture hours 0 lab hours 4 credits

Course Description
The transient responses of electric circuits are emphasized in this bridge course. Initially a variety of waveforms, including step, ramp, sinusoid, exponential, and impulse functions, are expressed analytically. The voltage-current responses of resistances, inductors, and capacitors to these waveforms are determined. Time domain differential equations and Laplace transforms are emphasized as circuit analysis techniques to determine the transient responses of first and second order circuits. An examination of transfer functions and pole-zero diagrams concludes the course. Note: This course is intended for transfer students and should be taken only upon approval of an EE program advisor. (prereq: EE 3001B, MA 235 or MA 3502)

Course Learning Outcomes
Upon successful completion of this course, the student will be able to:

Mathematically express step, ramp, sinusoid, exponential, impulse, and combinations of functions (composite waveforms)
Describe the electrical principles underlying the voltage-current time domain relationships for resistances, inductors and capacitors
Set-up and solve differential equations to determine the complete time-domain responses of simple RC, RL, and RLC networks
