Thank you for the reply. I do have one more question. After sending a positive edge on the watchdog input, I just bring that pin to "LOW" until the next time I send out a positive edge, correct? Sorry if this question is very simple. For some reason I'm having a hard time understanding this.

Hello, I'm trying to interface an Infineon TLE4263-2ES voltage regulator with a external watchdog figure. The microcontroller is from the Freescale S12G family. My question is kind of gereic, in a way. When I'm sending a pulse signal to the voltage regulator from the micro, at what frequency...

I believe the frictional force is a function of velocity, so Fb1 = B1*x1' and Fb2 = B2*x2' where x1' = velocity of M1 and x2' is the velocity of M2.

Yes, f1 is applied to M1 and f2 is applied to M2. The initial condition of the masses are at rest and spring relaxed. [f(0) = 0 and f'(0) = 0].

gneill, I actually didn't understand the problem correctly. The professor mentioned the input forces (f1 and f2) are the output and he said that x1 and x2 are the output. But then yesterday he was going over the this problem and he said you could define the input and output to be anything you...

The problem statement: I have to find the transfer function of a mass spring system. There are two masses in the system and 3 spring. I also have to find the state space representation and the model of the system. I have attached a image of my problem and my work so far. I think I found the...

Thank you for the replies. I think I won't go for a second undergraduate in CE. Perhaps I will do a Masters in CE but not sure. I think right now I will try to join some engineering groups and work on some projects, that way I can increase my experience in a real world environment.

Thank you for the reply. It would've been only 16 more credits for the second Bachelors if I had got it during my undergraduate but now it will be 32 credits (8 classes). I think I can finish the 32 credits in about a year. I'm looking for some practical experience as well some academic...

Graduated with a EE last May (2012). Currently working as an R&D Engineer in the automotive industry. 1. College experience was pretty good. For the most part I liked the engineering classes (and some humanity). The university I went to you could double major in almost any two majors but the...

Hello, I would like some advice on getting a second Bachelor's degree in Computer Engineering. I currently have a Bachelors degree in Electrical Engineering. I should've gone for a C.E. degree since it was only 16 more credits but I didn't think it would matter much, so I didn't. Now I'm...

You are right aralbrec. I gave up on solving the problem. I used Matlab to solve for it and it worked, :D. Well the frequency response looked correct in Matlab. I don't have the exact values Matlab calculated because I turned in my report and forgot to save a copy. But it turns out I did need H0.

I also solved the equation assuming H0 was 1 and the answers didn't match for the two points I have, so I understand what you were saying about it earlier. But I just wanted to see if that worked because that was easier to solve than two systems of equations with two unknowns, lol. And also my...

I solved the equation with H0 and got four different possbilities. This was using Wolfram Alpha because Matlab was giving me a lot of errors and I didn't feel like using it, lol. The answers I got are: H0 = 0.0000159160, Ω0 = -0.500008 H0 = -0.0000159150, Ω0 = 0.499992 H0 = -8.01142, Ω0...

There is no A given in the problem... So can I assume it's 1 or do I have to solve for that? I solved the equations assuming A = 1 and I got two different answers. When I solved for Ωz when s=jw=0 I got the answer to be 4.4429e4 or pi*1.414e4. When I solved for Ωz when s=jw=j2∏(10kHz) I got the...

Thank you for the reply. At 5kHz the mag. response is 0. At 0 Hz its 2 and at 10 kHz its unity (1). So I'm assuming the BW = \frac{f_0}{Q} and the bandwidth in my case is 10kHz, so f_0 = 2*10k, which means Ω_o = 2*pi*20k Am I correct? Then how do I get Ωz?
