I'm more worried about my electrical engineering final in 23.5 hours than I am about my dynamics final in 2.5 hours.

Of course, technically I eat my own words since I spent last year doing Verilog for classes and my Senior Project.

That is not our problem, that's your problem, entirely. If you can't even manage to get the studying done, what makes you think you'll be able to hold a job and do projects properly and finish them on time without running into problems like this? You're not going to be able to come here and ask how to do your work.

All i remember is that you use it with phasors. It's been about a year and half since i took that stuff and I have not touched it since.

Wow. This post is a blast from the past for me. Got my BSEE over 12 years ago, but always did computers and programming since then.. so forgot most of this stuff.
Seems a bit late to be trying to figure this out at the last minute for a final exam. Did you skip most of the classes over the semester?

I missed a couple of classes and when I came back, I was totally lost. I started to give up for the class until he told us that if we get an A on the final, we get an A for the class regardless of our homework and test average.
not sure. I'll learn both. I'm ok with transient analysis using diff eq's, but I'm sure he's looking for the use of phasors and whatnot. His problems will be very hard if I use diff eq's for steady-state. It's better to learn all that I can in this one day I have to prepare.

The most important thing to remember : the operational principle of the pn junction. Every danged device basically is a / contains multiple pn junctions. Well, Schottky barriers are metal-semicon, but the concept of drawing a band diagram is essentially the same (the work function of metal on one side, the Fermi level of the semi-material on the other).Originally posted by: NutBucket
Do you have a good calculator? Makes solving those RLC circuits quite easy.
Now, how about someone explain to me the modeling and operation of semiconductor devices?
ONE MORE FINAL!!!!
Basically, you put two materials together. Their original Fermi-levels will change and equalize at some value. So eg. for pn-s, instead of two discrete values you get a transition at the junction (band bending).
Oh nuts, gotta go. Will add more later
When you do AC analysis, current and voltage have both magnitude and phase. Therefore they can be represented by a complex number called a phasor. The frequency is assumed to be constant for the analysis.
This is like a very bad nightmare come to life.
Graduated 9 years ago with my EE. Haven't had to hear talk like this since.

The problem with me is I'm pretty good with ideas...just bad with calculations
if you don't know now you won't learn in time for your final. You are as fvcked as anyone has ever been - at least at Rice our fundamentals of EE class assumes you know imaginary number manipulation like the back of your hand coming in, and God help you if you don't.
Bah, like I said, all the PN and BJT calculations are straightforward enough if you have a formula sheet. MOS calculations for anything more complex than the square law become an incredible mess though.Originally posted by: NutBucket

Generally though, profs that aren't complete assholes don't try to screw you with computational difficulty on finals so it usually all works out OK

IMO, DE's are easier than LT's cause you can look at the equation and "guess" the form of the solution. No need to expand to partial fractions and take the inverse LT.
I'm 1337 when it comes to all the mathematical stuff. In fact, in a few short hours, I feel a LOT more prepared for this exam. I already DID know imaginary stuff like the back of my hand. Plus, after I got lost, I still kept going, keeping the stuff in the back of my mind...
"Well, if I can only understand what we just did, I think I see how it would apply here."
Have you ever heard of the "black box" approach to functions? It's when you use stuff without understanding it. I'm versed in both worlds. I like black boxing all the time only to later understand it for comprehension and long-term memory.

God bless an instructor who lets you use a calculator with a computer algebra system. (Gotta love the TI-89, especially when you get good at using it.)

You use LT's to solve DE's. It all depends on how you want to do it. Most of these forcing functions are trigometric (sinusoidal of some kind). Personally, I wish we were allowed to use numerical methods for everything. I wrote my own code to do that in my Dynamics final today. We had 6 problems. I completed five in two hours and spent the last hour coding my calculator to do a numerical result because I was getting braindead and frankly bored.
