    Thanks for posting this! I'm a student at Santa Rosa Junior College, and I'd like to use the segment between 0:30 to 0:52 in a student film called "Quantum". Can I get your permission to do that? I would, of course, acknowledge you in the rolling credits. Thanks in advance!

    In my experiments with this circuit I realized a couple of things. First of all. Y signal should be inverted(simple TTL/CMOS chip will do). In my case I got an inverted image (upside down). Second is some basic amplification and inversion of Z modulation signal. The signal was not strong enough to fully shutdown the trace. Other than that the circuit works decently.

    People there is an advanced open source Oscilloscope & Spectrogram software available:

    AudioCardDSP – Oscilloscope & Spectrogram (a Star Trek intro):

    Interpolation of surfaces from scattered data points (made in VB6):

    SigGen Ver. 3.1 (Visual Basic 6):

    Why not transmit low resolution TV pix at 29MHz with vestigal sideband transmission? How about adapting an old 14.4K modem = 15fps X 60Lines X 16/1(contrast) for this purpose?
    15KHz is within the audio band. The leftover 600Hz will be a guardband? Is this compatible with NBTV?

    I was doing this in the early '70s without the National Semiconductor LM1881, and with a Leader LBO505 scope. All analog TVs had Sync Separator circuits to remove the sync from the video. It provided H an V sync out, to trigger the scope's sweep circuits. It was more fun to feed the video out from my spectrum analyzer, to a video monitor and allow it to scan from 54 to 300 MHz to freak people out. 🙂
