You can also get a bode plot by solving the system of differential equations you get by mesh/nodal analysis of a circuit.
Yes, and the Laplace transform is how you usually solve them. That's what I meant earlier by using it to get to Bode plots, because when you go to the steady state, the Laplace variable s is just the same thing as frequency, j*omega. When you see an integrator in your circuit you just think 1/s which is a Bode plot sloping downwards at 6dB per octave.

So I just finished my circuits 2 class. The final was so easy... I was perfectly prepared for it...
5 problems, 1st one, get the z parameters for a TT resistor 2 port network. 2nd transform a load on a transformer to the input terminals... ideal transformers 3rd use s-domain to find a thevenin equ, I used source transforms in the s-domain 4th, node voltage 5th, natural response of an RLC circuit, this one was weird cause I got some Mega volts for a response with an 80v source, but the alpha was 100k sooo
yeah that was my test. I feel pretty good, so I am gonna spend the rest of the day, playing guitar and reading my books about solid state electronics.

But what if they aren't teaching anything? :)
He's a lazy professor, recites examples from the book, and if you even ask him one question, its like, you're dumb for even wondering. Not a good learning environment.
But hey, he's got connections to NASA so... best friends forever!

Look man... you look out for #1, okay. Don't worry about him, he's already got the job or money or whatever. All you can focus on is #1 and that's you. You follow that rule and you'll be okay. Don't pay any attention to him. After the semester is over you may see him 1 or 2 more times in your life and that's it. So just worry about yourself.

for sure, you're right! and honestly I was just venting. You know... its a whole semester of my time, listening to this guy, at 8am. I have to pass the class cause its a pre req. and I was sort of let down because I didnt gain anything from it.
but you're right. I wasn't sure if what we skipped was important or not. I do have a genuine interest in EE. And to make a super uber tesla coil is a dream of mine, so no worries man.
its a sensible guide to give me direction that I think I lack. I might need a mentor... but where does someone get a mentor?

For me, I get my motivation from the idea that the more I pass, the better I am as a person. Ive always had just an average IQ, yet have the attitude of one with a much higher one (so I am sort of "mentally handicap"), and have struggled in math. Whenever I pass a "hard" class, I feel better and better about myself. (Yea, calc1-3 was hard as hell for me, but I did it!). The encouragement from overcoming mental handicaps is what push me...I am in Circuit analysis 1 (well, I was. Its over now and I got an A!) Matt
