content: 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.

content: 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 .

content: 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.
