how to build a digital to analog tv converter

With analog stations, a weak signal can still yield a watchable picture-it might be snowy or have ghosts, but you'll get a continuous picture and uninterrupted sound. The all-or-nothing nature of digital broadcasts also comes into play. So getting good UHF reception can be more difficult than pulling in VHF, affecting your ability to get digital broadcasts.

(However, digital stations in some areas may move to the VHF band next February, when analog channels vacate their station frequencies.) The UHF band is more directional than VHF and more sensitive to obstacles (such as trees, tall buildings, and mountains) that lie between your antenna and the broadcast tower. Most analog stations are in the VHF band, channels 2-13, while digital signals are transmitted mainly over the UHF band, 14 and higher. Digital TV offers potentially better picture quality and more channels than analog over-the-air broadcasts, but getting digital signals might not be as easy as plugging a converter box between your antenna and TV.
