Hey, I've been working on this problem for a while now to no avail. The question is to choose R1 and R2 such that Vo = 10IsRx. I've gotten as far as solving for each input voltage for the op amps and their accompanying output voltages, but I end up with a huge expression in terms of Is...

I'm using Matlab, but have been unable to find any functions to do it. Are there functions in the Image Processing kit that I'm missing?

I'm curious about this lighthouse paradox, but I can't really find anything on it. Do you know any sources for further reading?

Hi, I'm currently working on an imaging problem that oddly requires some physics. Basically, I'm given a set of gray scale pixels and I have to determine whether they're a fiber or just random noise. My question is, how do I calculate the moment of inertia of the pixels while considering...

Hey, Does anyone have a recommendation for a good intro to differential equations? The book I'm using now (Guterman & Nitecki) is pretty bad. I'm looking for lots of examples, practice problems, and hopefully answers. Thanks!

I tried reading through AoE once, but it was way over my head. @Berkeman - None in particular, just a better intro EE book as a whole. The textbook I'm using now has really poor examples and very few practice problems.

Hey, I'm currently in an intro to EE course, and our textbook is horrendous (Hambley's Electrical Engineering Principles and Applications). Does anyone have a suggestion on a better alternative that provides a lot of practice problems/answers?

Find the equivalent resistance looking into terminals a-b for the network. Hint: first connect a 1A current source across terminals a and b. The solve the network by the node-voltage technique. The voltage across the current source is equal in value to the equivalent resistance. So I've...

Homework Statement A spring of spring constant k is suspended from the ceiling with a mass M attached to its lower end. The spring has negligible mass. Show that the sum of the elastic potential energy of the spring and the gravitational potential energy of the mass is a minimum at the...

Thanks for all the advice! I had a few projects in mind already: 1) Tangentsoft's headphone amp in an altoids box. It's watered all the way down, so I think it'll be pretty cool to try. 2) http://www.instructables.com/id/E6ZR3EFF1A4XWKA/. I think this one might be a bit harder, but I've...

Hey, Right now, my beloved TI89 is off in another country, so I was wondering if anyone knew of an open source calculator software that functions sort of as easily as a TI (not like Mathematica or something). Thanks.

So basically, I can't really do too much until I can understand every aspect about the basics? I'm still a semester away from differential equations, so I guess I have a long time to wait... I guess sort of another random question: exactly what will a general EE degree allow me to do? I just...

Hey, I was wondering if anyone could provide a bit of a learning roadmap to help me eventually build and understand circuits. Someone suggested The Art of Electronics, but it's a bit over my head. I've been reading http://www.ibiblio.org/obp/electricCircuits/index.htm , but because the book...

Homework Statement A tall uniform rectangular block sits on an inclined plane. If Us = .4, does the block slide or fall over as the angle is slowly increased? Also, the block is 3a units tall and "a" units wide. The Attempt at a Solution Just by intuition, I figured that it would tip...

"A student was given a .1 M solution of an unknown diprotic acid, H2A, and asked to determine the Ka1 and Ka2 values. The student titrated 50.0 mL of the .1 M H2A with .1 M NaOH. After 25mL of NaOH was added, the pH of the resulting solution was 6.7. After 50 mL of NaOH was added, the pH of...
