I don't suppose that there are any electrical engineers out there who can describe how to create a Bode plot from a transfer function? Because that would help, and I have a final at 8:00am Tuesday.

And for the life of me, I can't imagine a situation in real life where I would ever have to create a bode plot from scratch

OMG How so fucking helpful!!!

I understand everything now! The reason why I could not create bode plots before was due to the fact that the universe did not in fact exist!!!

Now I understand everything! The secrets of creation are all unfolding around me, and the mysteries of the universe are all unraveling!!! I feel a massive pulse of enlightenment washing over my mind!!!

Who could have possibly imagined that some obnoxious troll post on 4 chan could have unlocked a virtually transcendental understanding of the universe!

OP, bode plots are best described with an example... first factor out shit and make it in the format of a(1+jw/a)
for H(w)= [a(1+jw/a)/b(1+jw/b)], easy way to solve without understanding... take each factor and draw them separately on the w-f(w) plot, then add them to get the solution.
Draw the a as a straight line parallel to the omega axis and label it as 20loga dB, for the other factors, (1+jw/a), draw a straight line on the omega axis then when you reach a on the w axis, draw a line at 45 degrees in the positive slope. For (1+jw/b), draw the same thing as (1+jw/a) except instead of a positive slope, draw a negative slope. Finally graphically add all 4 factors together to get the bode plot.

Thanks bunches, I have been following the examples here:

http://www.ece.utah.edu/~ee3110/bodeplot.pdf

And I get that the first line starts off at 20log(K)

And that the zeros break from this line and cause a divergence upwards at 20dB/decade

And that the poles do the same thing, except downward at -20dB/decade

And that I basically add up all the +20 slope and -20 slope and figure out what the slope of a line is at any given point.

The only thing that I don't get is where to start the line at?

As somewhat expected, the boss of Black Lotus eventually decided to stab me in the back, give up on their promises and cave in to the trolls, being extremely unreasonable about it all. Just as with PRQ (who didn't do a thing about a DDoS attack for three weeks or even respond to me at all, until I was forced to move as the site was to remain offline indefinitely in their incompetent hands), he didn't technically kick AT out, but in practice, by demanding random censorship of legal discussions (while ignoring the abusive customers) in a way which very obviously and without any doubt purely served to get rid of AT. Trust me: it was not a real choice and I wouldn't have any respect for a site admin who gives up on his core values, just as I have absolutely zero respect for subhumans who lie and stab others in their back.

So: I simply cannot host the damned board anywhere on this planet, unless I somehow manage to afford my own data center, ISP and enterprise-grade equipment. I'll try to make that happen ASAP, but it's not easy. I've known for quite some time that AT was never going to make money on its own, and requires massive external backing in some way. If one of you were an eccentric billionaire, you would've stepped up by now. Truth to be told, I really did honestly believe that a major anonymous supporter (who naturally would get to remain anonymous if he/she so wished) would step up at some point and save the best forum on the Internet from this very sad fate.

The worst part is perhaps that I'm fairly sure that with steady donations from you, I could've afforded a much better server and DDoS protection, and thus the greedy fuck running Black Cunt (actually, the main employees were always very competent and friendly, so the only bad thing I can say about them is that they work for the devil) might very well have not started harassing me as AT would've been a good customer, bringing in lots of green ones for him to swim around in and masturbate to.

Back to this post, it all makes perfect sense, I just need to know where to start the final bode plot line off at.

And also, along the omega axis, where do I usually start numbering on the logarithmic scale? It suddenly occurs to me that there will never be a "0" on a logarithmic plot axis.

I didnt accidently her trip. she isnt even here. she probably isnt even awake.

she had been posting here just as harriet but without a trip for some time, despite my advice. so a few days ago she was impersonated (simply by some anon writing harriet in the name field) and i got trolled because i couldnt tell it wasnt her. then i finally convinced her to trip, so she did. she had picked some fucking stupid tripcode, and some anon managed to decode it and impersonate her yet again.
now she has changed it to a tripcode that isnt as easily decoded, and reads as 'gogo spy' or something like that.
the one that the harriet used in this thread was her first one that got decoded. the anon trolling in this thread must be the same person who figured out harriets tripcode, which is why he is using her old one.

so try to quickly delete it.
it still was the wrong tripcode, if harriet and me were the same person, why would i not use the most recent one?
if we were the same, why would i make one of us stupid and not use a tripcode for several weeks?
