BF2S Forums Math problems

Short and sweet, and especially clear!: Some gay Calculus or whatever shit that is totally un-understandable to regular human beings (This excludes geeks, nerds, bookworms, math lovers, teachers, and Albert Einsten), which doesnt help with anything you will ever do in your life...pwn3d

It's 1+1=2. It's that easy

I think my head just imploded.

_{*My fingers are currently writing this by muscle memory since I no longer have a head*}

I think my brain was jihaded by my my white blood cells.

Who needs karma i do. I'm 14 and proud of it.

It's about changing time and the formula on how... thats all. Karma me now bitches

I know the Z transform and my head has still also imploded.

Its like the Fourier Transform or Laplace transform but for discrete signals, e.g. non-continuous (think digital). It's analogous (har har) to math used in analog systems. It is extremely useful sadly, so you are gonna have to learn it if your in comp/elec engineering.

Just did that shit 2 terms ago for signal processing courses - it's actually pretty easy as long as you remeber partial fractions expansion and some barebones methods to solve. Do not do the Z-transform by hand if you can avoid it or you will be dealing with way too many cases, just do partial fractions and use the residue formula.

I was gonna say this. You beat me to it.

fence?

In effect its a complicated modem sorta thing

some sort of algorithm...

Ok.. I nenglish (not my first language, so bear with me if I make a mistake:

First of all, when talking about a Z-transform, you ALMOST always mean a UNILATERAL Z-transform. So you can forget the others.
For electrical engineering it's nice to remember that laplace (as someone mentioned) deals with the DIFFERENTIAL equations and s-planes, where Z-transform deals with DIFFERENCE equations and the z-plane. However, the two are not identical, as the S-plane is "rectangular" where the Z-plane is "polar". In essence a Z-transform is the basics in a recursive digital filter !
Now if you're a student of electrical engineering, I guess that's about all you need to know to really understand it. The math behind it is a bit more complex to explain without an example. This link will give you a little more insight than the wiki:

If it's the MATH that's a problem, post again, and find out how many math buffs there truely ae in the BF2S forums (I'll bet a LOT)

okkk new question


what does this mean 0<a<1

what does that mean oh and im doing work on functions y=-af (-k (x-h)) + K

that stuff
