Engineers Needed in Charlotte
We live in an ever changing technology world – and the Engineers of tomorrow (especially the electrical and computer engineers) will lead the way Comparison of 1973 to today 1973 (the year I graduated with a BSEE) n n n n n Jet travel -747 Jet Skyscrapers Long tall bridges Modern highways Transistor radios GM, Ford, and Chrysler dominated the market -very powerful engines but poor quality Color TV – 25 inch 4 TV channels – ABC, CBS, NBC, PBS Space travel – first man on the moon in 1969 CB radios – 14 to 28 channels total 8 -track audio tape players Slide rule for scientific calculations Typewriter for reports One phone company – ATT, the Bell System Industrial computers - tape or punch card programming Film cameras and expensive developing Libraries Early satellites
How numerical calculations were made in 1973 A slide rule
How phone calls were made in 1973 A classic Bell Telephone black rotary home phone
How reports were done in 1973 A classic typewriter
How photographs were made Film Camera with film cartridge

Space, You. Tube, etc. Space travel via shuttle with orbiting space station High quality autos build with robots Autos with on board computers, ABS, GPS, emission controls, radial tires, air bags, crash avoidance systems, etc.
Not only is technology ever changing but it is getting cheaper and cheaper Example n On 12/13/95 I purchased for Christmas a desktop computer with P-75 processor for $1499. 99 and a HP 660 Desk. Jet printer for $379. 00. Total of $1, 878 n Today a computer 10 x faster with 100 x more memory and a better printer can be purchased for around $300
Some laptop prices
More laptop prices
What would you rather have? A computer or an X-Box 360 $398 $399. 92 Laptop computer X-Box 360 AMD Sempron Processor 60 GB hard drive DVD/CD Burner Basic programs Wal-Mart Ad One controller NO games Games typically $60
You – the electrical and computer engineers of tomorrow will be the drivers of future technology And may become very, rich
The list is dominated by technology and note the lack of entertainers, sports figures, movie stars, etc.
Engr 1201 vs. Engr 1202 E 01 is specific to electrical and computer engineer n Engr 1202 E 01 will only deal with electrical and computer engineering topics n There is no textbook with Engr 1202 E 01 – all necessary information will be provided in class – Either at my web site, coefs. uncc. edu/jahudak/ or Dr Conrad’s Moodle site n Engr 1202 E 01 also has a Recitation / Problem Session on Thursday evening taught by the ECE Department Chairman. The class does not meet every week, only as scheduled. n
Goals For This Class n n n n To make this class interesting and fun To give you a better understanding of today’s technology as it relates to electrical and computer engineering To get you excited about engineering, especially electrical and computer engineering To provide a stimulating and informative learning environment To provide you with an interesting and unique experience of working in a “clean room” To provide a hands on laboratory experience that relates to real world conditions For you to finish this class with a strong desire to continue in electrical and computer engineering
