What is it?

A fart

The mains in India.

BBV? (bad baseband video)

The clock line of an 87-V adjacent to a GSM phone?

back emf from something being sent different length square waves ?

I see waveform that does not utilize the full amplitude range of the scope.

What is it?

A push button being pressed with bouncing effects. The trigger of the scope has a pre-delay... since there's a little arrow in the upper left corner.

something having to do with Tiffany Yepp.

Dave's ECG when he rants.

That waveform was captured on an oscilloscope in one of the Zachry labs at Texas A&M. It only shows a small part of a very complex waveform.

is that the answer ? if it is it's damn dissapointing or was that a clue - but I'm still clueless

NiHaoMike · « **Reply #12 on:** September 20, 2010, 08:04:42 pm »

It's just a hint. And it has nothing to do with Tiffany Yep.

Simon · « **Reply #13 on:** September 20, 2010, 08:10:11 pm »

wouldn't it be more sensible to show us more of the wave or would that give the game away ?

This is an voltage graph under unstable amps load .

That would probably give it away.

The EEVBlog uptime?

Kiriakos-GR · « **Reply #17 on:** September 20, 2010, 08:51:52 pm »

Logically its an wave that lasts 10 seconds or 10ms .
And has an very fast deviation , its no sound , its no frequency , its pulses , it could be an digital siren .

Looks like Dave's clipping audio!

Another hint: a FFT:

Zad · « **Reply #21 on:** September 22, 2010, 02:56:57 am »

I reckon that peak is the NTSC colour sub-carrier on 3.58MHz (fooled me because PAL is on 4.433MHz), so the waveform is a video scan line of something, minus synch pulses.

That's what it is, technically.

The actual answer is what my friend Allie Moore looks like on an oscilloscope.

Well that was anticlimatic.

Is she female and attractive? If so please post a picture, if not please don't post a picture.
