> We hit a strange truth about analog monochrome television: the vertical resolution is strictly limited: it’s the number of lines you draw. But the horizontal resolution, the resolution within each line, is basically infinite; it’s a purely analog signal. The only thing that holds it back is how quickly the electronics in your television can keep up.
No, it's strictly limited by the bandwidth of the television signal. You could have infinitely responsive circuitry but you'd still have horizontal resolution limited by the bandwidth of the video portion of the broadcast TV signal.
About all you can say is that analog TV does not have pixels.
Anyway, here's a video (part of a series) on how analog TV works:

- TazeTSchnitzel 5y agoThose aren't really pixels though: the signal can (and does) vary within them.
