http://www.tricojvs.k12.oh.us/eng/resour... In the telecom world, understanding analog versus digital isn't as simple as comparing one technology to another. It depends on what product—and in some cases, which product feature—you happen to be talking about. Analog is the old electrical way of doing things. When you are talking digital, you are talking digital signals in 1's and 0's just like in a computer. It involves computer chips. The analog way of volume or tuning control has to be a slider or nob that turns or "physically" moves up the contacts to adjust. With Digital, the chips do the work they are programed to do with each button you push. This is way simplified, but that is the basics.
