How good is DTV at rejecting adjacent channels?

If two channels lie next to one another, like 43-strong and 44-weak, that the stronger station would cause reception problems in analog television.

ATSC/Digital television claims that would not be a problem.

Why? And how well does it work in the real world?

That was a big problem with analog signals. For that reason, few stations in a market could be next to each other.

With digital, stations are broadcasting on a special set area so they don't overload their subchannels. Same thing with HD Radio.

Ask the people in El Paso Texas, they have DT stations on channels 15, 16, 17 and 18. 15 and 16 are at 1000kW, 17 is at 950kW.

Digital broadcasting is very good at rejecting adjacent channels, that is why the FCC is able to do away with channels 53-69 and cram all the existing and future channels in the 2-52 channel range, most of it in the 14-52 area.

Actually it is the 52-69 range that is being done away with. Effective February 18, 2009 TV broadcasting will be restriced to 2-36 and 38-51 (49 channels overall). Channel 37 has long been reserved for radioastronomy usage and will remain so.
