Electrical Engineering: Past and Present

AI Thread Summary
Electrical engineering education has evolved significantly from the 1950s to the late 2000s, with modern curricula emphasizing semiconductor physics, digital technologies, and software skills. Graduates from earlier decades typically had a stronger foundation in analog circuitry and traditional components like BJTs and amplifiers. The introduction of computers has transformed problem-solving, allowing for more complex analyses to be conducted with ease. Despite these advancements, fundamental circuit analysis techniques remain consistent over the decades. Overall, while core principles persist, the focus and tools used in electrical engineering have adapted to technological advancements.

Would an electrical engineer who earns a B.A. in Electrical engineering from around say 1998 - 2009 going to be taught different concepts than an electrical engineer who went to college say in 1950 or 1970 ? What are some of the differences?

I would seriously doubt it. Technology has changed so much since then that I would guess that everything but the fundamentals has change. Digital electronics for example. And don't forget things like power transistors and IGBTs. Computers have also made analyzing some of the most difficult problems a walk in the park.

I got my education in the 1950's, and my only EE lab electronics course covered thermionic emission and pentode amplifier circuits (Q to Forum Admins: why does your spell checker underline "pentode"?). If I got my education in 1970, I would learn about germanium and silicon BJTs, PDP-8 "flip-chip" computers, the Fairchild uA 702 and uA 709 amplifiers (and uA 741?), and SN7400 series digital gates. The HP-35 pocket calculator was still 2 or 3 years away, (and cost ~$395).. I quess few readers ever heard of Amplidyne power amplifiers (dc gain ~10,000 and unity-gain bandwidth about 100 Hz).

To a degree, yes. Today, an EE would be exposed to more semiconductor physics. Also, digital, and software gets more attention these days. The EE who graduated in 1950-1970 may more than likely have a stronger background in analog circuitry than a recent EE grad. But, a recent EE grad is more likely stronger in software, and semi physics.

Both should be well versed in math, controls, and fields.

I'm confident the answer is partly. I'm somewhat of an engineering historian, and I've seen plastic calculators that were specially designed for analyzing second order systems. When I went to school, we used mainframes to run Spice as a batch. Later, the kids were taking Spice and control systems programs home to run on their PCs.

Now, I know more recent graduates that leave knowing VHDL and are ready for digital-hungry world.

Then again, some things don't change much. I have an old edition of the General Electric A-Course and it pretty much teaches the same circuit analysis techniques you'd get now.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Electromagnet magnetic field issue'
Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...
