Default Is this UHF tuner analogue or ditital ?

Without foreknowledge about the make and model of TV or PVR or whatever ,
and not powering up with a signal, any probalistic indicators?
Date ?
Size ? eg cigarette pack size analogue versus match box size
multiplex/digital ?
Are there dual tuners that could hande both conventional and multiplexed
signals?

+++++

I'm thinking cas boot sale or hamfest seller/buyer situation
In the UK after this march then cost next to nothing , if an honest
seller - analogue
Much spondulics, again if honest seller - then digital.

Back in the days of the GRAND TV switch to ATSC, I carried a card in my
wallet
listing all the settop boxes that could do OTA ATSC. There weren't very
many.

"I'm not sure", is a pretty good indicator that it's NOT.

If it's just a tuner (i.e. IF out), I'm not sure why it should matter.
ATSC was specifically designed to occupy the same bandwidth as analog,
so a decent tuner should handle either. The only possible problem might
be if the local oscillator has a lot of phase noise. That would not
bother analog, but could mess up digital.

Any demultiplexing would take place later in the signal path -- after
the signal is decoded sufficiently to allow discovery of information
relating to the multiplex.

** ATSC is usd in Canada and the USA.

The UK, Europe, India and Australia use DVB-T.

** Correct.

A modern UHF tuner for digital TV is likely to be very compact.

The term " digital tuner " is used in the trade to describe digital TVs with
antenna inputs.

Is this similar to, say, plenty spendolas?
