Digitial TV - why does it lose reception in distinct cycles?
posted by Jimbob to technology (8 answers total)
We've got pretty poor DTV reception, we're behind a hill, and use an indoor antenna. In particular, for one station group, we often get poor reception when we're walking around certain parts of our house - the kitchen, for example. So the rule is; stay on the couch if you want to watch.
However, the way the reception breaks up is weird. The audio disappears in cycles with a frequency of approximately one second. So we get half a second of perfectly clear sound, then half a second of silence, then half a second of sound, then half a second of silence. Why would it happen in this way?
