    Did you mean for the title to say analog?

    Analog signals (though a scientifically beautiful way of combining luminance and Chroma information) were always dnoisy by default.
    If you are having problems with digital, you have a poor installation or a poor caable provider. The resolution and lack of noise is a huge step up from analog.

    I don't know if newer TV's even include an analog input (you'd have to check the model) but my 3 year old LCD does...except I don't think anyone broadcasts it anymore around here (NYC-PHIL markets)

    IIRC, some countries have not yet converted.

    I keep an old analog TV around to track lightning, and view the CMBR.

    Digital signal need a perfect reception (or the screen will be garbled like a broken CDs), but an analog signal you can still watch TV with a very very bad reception. (I think) white noise is not a problem as long as you can still make sense of it, but a garbled screen (ie: broken CDs) are not even comprehensible/not-watchable. In some places you need to live with bad reception; which is bearable if using analog signal.

    Also digital signal is a compressed and appear blurred if not in HD.

    Also,
    Tube TV + analog signal produce really nice low-res picture. (but low-res picture + LCD => Ugly )

    Digital signals are pretty fault tolerant, up to a point. An analog signal would be almost unwatchable at that point. But once the error correction can't keep up, it goes to hell real fast.

    I worked in the TV biz (for broadcast equipment and test and measurent equipment manufacturers) from the black and white era through the digital transition, so I've seen it all except developments in the last 3 years or so.

    An analog broadcast signal at no point contains the resolution possible in a digital picture, especially in the color data.
