Hi, I was wondering if anyone could recommend a good solid book(s) for self study of electronics design? I emphasize design because I recently finished an electronics course in college and have found that I am decent at solving book problems but horrible at designing circuits. I still have no...

Hello everyone, I've been experimenting in MATLAB, attempting to create a flanger type effect. I would assume that the flanger is already included in a toolbox but I would like to create one on my own for personal satisfaction. I've been reading up on flanger operation but I've had trouble...

Hi, I am looking for a really good book that I can use for self study of algebra. I would like the book to contain topics from both algebra 1 and algebra 2. I took both algebra 1 and algebra 2 in high school and did very well in both. However, its been several years and there are certain...

Homework Statement I came across this expression in homework and for the life of me I can't figure out how this evaluates to 0: 1 - ( -i )^-4 = 1 - 1 = 0 I know that i^1 = i, i^2 = -1, i^3 = -i, and i^4 = 1. I'm just not sure how to treat the negative on the i. Do I just treat i as if it...

Hi all, I am enrolled in an introductory signals and systems course at my university. I don't like talking down on my professors but in this case I can't help it. He is one of the worst teachers I have had in my life. I have visited his office hours but he's not really helpful in there...

Homework Statement I'm working on a problem where I have to add two phasors together. The problem is, the real parts cancel out and I can't figure out how to express the phase because arctan(y / 0) isn't defined. Homework Equations x1 = 10<45 degrees x2 = 10<135 degrees x1 + x2 =...

Hmm, that makes sense. The weird thing is, i took arctan manually with my calculator and got -38.2043. However, when I put the entered the number into my calculator as rectangular and let the calculator convert it to polar, it knew to print 141.79.

Homework Statement I was working on a problem dealing with complex numbers. I had to add two phasors together to get the combined phasor. I converted both numbers to rectangular form, added them and converted the result back to polar form. My magnitude was correct, but my phase was not...

What are the "coefficients"? What do they represent? Are they amplitudes of the sinusoids? Thats what I don't understand. The professor asks to find the coefficients but doesn't explain what they are.

Complex Fourier Series Coeffcients; what are they? what do they represent? Homework Statement I'm not sure if this is the right place for this but it seems appropriate. I just started an intro signals and systems course at my university at the beginning of this semester. We started Complex...

1. Homework Statement f(t) = (sin(2t))/t Homework Equations 3. The Attempt at a Solution I know that sin(t)/t has the Fourier transform pi(w). I'm just not sure how to apply that fact to this problem. Knowing that sin(t)/t --> pi(w), I reasoned that sin(2t)/t --> 2pi(2w). I'm...

Hmm, so in the real world its not so much "here work these 20 integrals out on paper that will take you forever to figure out"? As long as you know how the math works and what to input, you mainly put it into a program of sorts and implement the result?

Hey chroot, Thanks so much for the reply. At the university I'm transferring to, the computer engineering program has a hardware and software specialization. I chose the hardware specialization. I looked at the class lists for EE and CPe hardware and they are pretty close with the exception of...

Hello, Since about 10th grade, I have wanted to be a computer engineer. I love working with, on, and around computers. I seem to have a knack for computer related "stuff". I have decided to pursue a degree in computer engineering with a HARDWARE emphasis through the University of Florida. I...
