i think you all missed the
actual asked question
and if you read what i types - my spelling errors
you will see i fully answered it
am and fm tv is highly used
in the us
but digital tv systems are sole invented and patented by the uk...tv industry
therefore only licenced to countrys to use
much like any analogue system
am and fm dosnt support digital tv signals as such
and requires a digital dds or ddc to do the modulations of the bytes for carrier encoding
as i pointed out
and i thought was what the guy asked
maybe i am wrong
:roll: im only human and never watch tv signals
only on a scope for 20 years or so
so realy i know nothing
but you pointed out all the things i said anyway were fact ..... not fiction
Double balanced mixer can be used for modulation process but carrier signal with proper amplitude must be added.
you never add a carrier
you add to a carrier
or intermodulate a carrier
so Borber sorry your terms are way wrong
Within pure TV signal dependent on encoding system
???artem pure signal???
this is a contradiction
there is no such thing as a pure !!!
it is like 0 it dosnt exist and is only convinient
flatulent
i see you interprited what i said
i didnt have all night to write a good text and had planned to edit it later anyway
to add some more info
however
The US 1kW limited coverage stations hahahahahahahahahahahahahaah
ANY us radio ham has a trilawatt amp and a very loud mike
i cant beleve any tv station just has 1k input
unless they transmit down the street 100 yards
so i guess with a good slot
thats what 220,000 watts erp ??? or more on a hot sunny day .....
i know this already other than adding the word america {these guys think they are so cleaver
so cleaver we in the uk had to show them how to build a computer and supply them tv and make a standard for them
they do use a pathetic ntsct system
never the same colour twice
america is a long way away and i dont like american goverment policies anyway......
i rest my case....!
