  • Are you sure it was dot pitch and not dot clock?

    Dot pitch on a crt might make the image look bad (trying to draw onto the shadow mask) but I doubt it would damage it.

    Setting an invalid dot clock could damage some crts. But most of the modern (read from mid 90s on) would just go to the power save mode when they got a clock they couldn’t use. The warning did still remain on the xfree86 configuration guides though.

    Showing my age perhaps.







  • I think my question on all this would be whether this would ultimately cause problems in terms of data integrity.

    Currently most amplifiers for digital information are going to capture the information in the light, probably strip off any modulation to get to the raw data. Then re-modulate that using a new emitter.

    The advantages of doing this over just amplifying the original light signal are the same reason switches/routers are store and forward (or at least decode to binary and re-modulate). When you decode the data from the modulated signal and then reproduce it, you are removing any noise that was present and reproducing a clean signal again.

    If you just amplify light (or electrical) signals “as-is”, then you generally add noise every time you do this reducing the SNR a small amount. After enough times the signal will become non-recoverable.

    So I guess my question is, does the process also have the same issue of an ultimate limit in how often you can re-transmit the signal without degradation.
