I wanted to do a small write-up on a local forum as to why square signals carry more power than the same amplitude as sine-wave signals but can't remember how to work with integrals....so it's time to go back to my notebooks from high-school. It's amazing how easily you forget something you don't use :(

What do you have to do with integrals? Evaluate between two points?

Are you evaluating an integral for a sine function, finding the area between two points. Then evaluating an integral for the square (clipped) signal, finding the area between two points, then comparing the difference?

I think a square wave is around 41% more power then a sine wave?

sine wave rms = peak*0.707

square wave rms = peak, or 1.414*sinewaverms

Assuming of course, their amplitude is the same.

You are correct on that. I just wanted to re-do the math behind it. 0.707 is plenty for showing what happens.

Basically I need to find out the area under the sine wave graph between 0 and PI and the sine wave is A*sin(wt). Damn memory, I can't do any integral :lol:

You can pull out A when you find the anti derivative, then multiply the anti derivative by A.

-cos(wt)/w + c would be the anti derived of sin(wt)

Then throw the A back in:

-Acos(wt)/w +c

Now evaluate from [0,π]

-Acos(w0)/w + Acos(wπ)/w

Assuming t is the input.

:thanx:

t is input, correct :)

Slap me. I know Billie D, and I've seen the last guy on some shows on history. Pretty awesome dude, but I have NO IDEA who the first guy is.

What the god damned shit stained fuck? Porsche is saying their Panamera can tow 4850 pounds??

Well this is awkward:

Sweet! Since I decided to sell my house and move I don't need a truck for the boat anymore and that means I only really need to tow the snowmobile trailer. Maybe my next car :P

Snowmobiling > all.

God damn its fun. Power to weight that is absurd and a medium that allows you to fuck up and not have it be a deal.

Dirt bikes are fun, don't get me wrong, but everything you like about them is better on snow. Including normal rider comfort in the environment.

I have a hard time with control on sleds. But I'm sure if I had the same amount of experience on a sled I would enjoy it. For now, i'll stick with two wheeled machines!

I saw a Panamera at the expo. I hated the way they looked when I saw it on Top Gear, but it's pretty cool up close.

I'm sure some of the similarities on the snowmobile would be more extreme, thus more fun, such as drifting around corners. I just love the feeling of being leaned up on the gas tank, dive bombing into a turn, inner leg extended out, bike leaned way way over, and accelerating out.

One of my favorite parts is going through big well spaced whoops. Hit first one, lift front end into the air, wheelie over the top of the next whoop, set front end down, hit next whoop, wheelie out, etc.

Plus I have all the desert to ride. If there was snow instead, I'd probably get a snowmobile. Yours a two stroker?

Rode yesterday at one trail, rained, lots of traction. You could lean it, gas it, it'd stick. If you really wanted to break traction and slide, just bang on the throttle a bit more.

Rode today at a different place, no rain. Sliding everywhere. Sliding into bermed turns was a hoot, but flat - off camber turns was sketchy. Then I noticed my rear tire was so worn it had no nubs left. :lol:

The funny thing is that he was in the film just above your quoted post. Anyway, it is Carl Sagan, you know the 2nd, and Neil DeGrass Tyson. NDGT picked up where Sagan left off, as the great astrophysicist that brought the science to the masses though clean and clear concepts and proof. ;)

I know OF Sagan, but have never seen a photo of the man.
