DC current and Digital TV signals are both carried by a square wave. AC current and the old Analog TV signals are both carried by a sine wave.

In 2009 analog signals were turned off in favor of digital. The problem is that DTV signals are binary. Either you get a perfect signal or you get no signal. Analog signals are multipath. The picture might not be perfect, but at least you get a signal.
