Made it through one third of the fall semester! This week had the opportunity to test what I’d learned. Two quizzes and a midterm started off Sunday, Monday and Tuesday. Still waiting on scores for my EEE241 midterm and EEE334 quiz. Hopefully I did okay on them.
Aside from the quizzes and tests the lectures and homework assignments and labs continue.
EEE 334 Circuits II second lab was due Thursday. This lab covered operational amplifiers. It was really neat to apply the theory to four different op amp circuits. The lab looked at inverting and non-inverting configurations as well as integrating and differentiating applications. I keep thinking about audio applications and what I could build now that I have this new found knowledge. Reflecting back to the Arduino MP3 project I did for a local Sacramento artist over the summer, I definitely now have a much better understanding and have a few ideas on how to improve if someone is ever in need of another Arduino MP3 player for a kinematic painting.
The lectures in EEE 334 switched gears from diodes and moved into MOSFETS. These were a bit overwhelming at first. I was having the worst time with them earlier in the week, but one of the TAs finally got back to me and helped clear things up. I’m finding that as I move higher into the curriculum at ASU, there aren’t as many tutoring options available. Seems to stop at Signals and Systems I. Hopefully that is something ASU is working on, but right now, not much outside help is available.
The lectures on MOSFETs covered the following topics:
- Creating a channel for current flow
- Operating as the drain to source voltage is increased
- NMOS MOSFETs
- P-Channel MOSFETs
- Current-Voltage characteristics
- Finite Output Resistance in Saturation
- MOSFET Circuits in DC
- Lots of examples
Doesn’t look like we’ll have a lab on these for a couple of weeks, but looking forward to working with them more. The next lab I’ll be starting early next week is on Diodes. The homework on MOSFETs has five different circuits to work through finding various currents, resistances and voltages and determining what will keep it in saturation, etc.
EEE 241 – Fundamentals of Electromagnetics- the first midterm only covered one chapter, but looks like midterm 2 will have material from 4 chapters! Rumor has it that it is a beast. I have been a horrid student and have been just doing the bare minimums on the newer material trying to master the material needed for the 1st midterm. Now for the next four weeks, I’ve got to buckle down and really focus in on the material now for midterm 2. The tests in there are worth so much of the grade, hopefully this strategy pays off. So far so good on the homework, but definitely not as comfortable as I’d like to be. I’m hoping by working many of the problems in the book, I can make it through in one piece.
This week though, we’ve been looking at:
- Capacitance and Capacitors
- Electrostatic Energy
- Electrostatic Forces from the Energy of a System
- Poisson’s and Laplace’s Equations – Uniqueness of Solutions
EEE 230 Computer Organization and Assembly Language – Week 5 has been all about Pipelining. I have some work to do this weekend to get through the assignment and a few more of the lectures. I was distracted earlier this week on the quizzes and midterms. The lectures compared the single cycle model and pipelining. From there, looked at the pipelined datapath and control necessary. Naturally there are data hazards so looked at forwarding and stalling and then control hazards. There hasn’t been much work in the MARS Assembly Language program lately.
A bit more scary is the professor posted information on the final exam for this course! That is coming up October 8th. There was a nice outline though of what to study in order to prepare. It’s open notes, but no calculator or textbook. I will start next week on preparing for it. So far, I’ve done well on all the quizzes and the assignments and hope to finish strong in there.
Lastly, I’ll be registering Monday 9/25 for spring classes already. Trying to figure out how its that time again. At this point, I’m leaning towards the following:
- EEE 350 – Random Signal Analysis
- EEE 333 – Hardware Design Language/Program Logic
- EEE 335 – Analog Digital Circuits
EEE 333 and EEE 335 are two area pathway courses. I need to take four out of six possibilities. Both look to be four unit classes and have lab components so I imagine that Spring will continue to busy, but at least all of them are full semester courses.
