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. An electrical inverter is used to to turn DC current into AC current. Is there a way to modify an electrical inverter so it could do the same for OTA TV signals?5 AnswersEngineering8 months ago

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.
Is there a way to convert the digital signals back to analog once they reach you?6 AnswersTVs1 year ago
