There are many digital circuits on most electronic equipment.

High Definition is one of those digital circuits.

Actually, High Def has nothing to do with whether the cktry is digital
or not. A set can have ALL digital components in it but still only be
capable of managing analog TV signals. It's the TV signal that becomes
digital for HDTV, so the set requires a tuner which is capable of
receiving and handling digital signals. And it will of course, use
digital components; it'd be a bear to design an analog digital TV signal
receiverG.

So a tuner that can handle a HD broadcast signal isn't digital?
That's news to me.
