What is an Electrical Engineer (EE)?

An EE - application and control of electric and magnetic fields to produce and improve current technology*

Someone trained in the practical application of electricity*

Types of electrical engineeringo Powero Controlo Electronicso Microelectronicso Signal processingo Telecommunicationso Computer engineeringo Bio-electrical engineering

What does an EE/CE do?They design, develop, analyze, and test

o Computers and systems with computers embedded in themo Two-way communications systems (telephones and fiber-optic

systems)o One-way communications systems (radio, television, satellite)o Control systems (aircraft collision-avoidance systems, medical

electronic devices)o Systems used for the generation, control, and delivery of electric

power (homes, offices, and industry)o Systems that educate and entertain (computers and computer

networks, compact-disk players, cell phones, and multimedia systems)

Analyze computer-aided tomography data (CAT scans), seismic data from earthquakes and well drilling, and data from space probes, voice synthesizers, and handwriting recognition

EE/CE degree at FIT

Two programs: EE and CE Significant overlap between programs Large number of research faculty General research areas (EE)

o Electromagnetics (Lail, Mushid)o Electronics and optics (Grossman, Murshid, Earles)o Systems and information processing (Kozaitis, Anangnostopolous, Kepuska)o Wireless communications (Mu, Kostanic, Otero)

General research areas (CE)o Wireless communications (Otero)o Bid data and parallel processing (Otero, Smith)o Computer design and reliability (Saquib)o Leering systems (Anagnostopolous)

ECE Department offers advanced degrees (MSEE and PhD) ECE Department has a very strong connection with local industry (Harris, NASA,

Analex, QualiTest, Intersil, Boeing, and many more)
