It's still a trick, albeit a passable one.
Not much more than line scanning or TV PAL where you can send signals fast enough
to appear to the human eye as a continuous sequence as to appear continuous.
Do it fast enough and it scores a pass, nothing wrong with that.
But it will always be just slightly behind a true anallog signal in the *academic* sense.
Digital representation is exactly that, a representation.
Digital will always second to analog.
Done fast enough then the human ear can;t tell the difference, but that depends upon
transmission resources.
Shannon theory of? communication blah blah come into play too.
Bottom line is that *if* transmission is done fast enough then it scores? a pass.
Too slow then the transmitted audio is crap.
Thankfully using the STM stuff in newer kits should produce some very acceptable stuff
on the future, and fitting SSB into a basic CW/Data rig should be a nice bonus with
acceptable quality, nice.
But just remember, anything digital = quantization.
It;s always a *representative* of the analog, an incontrovertibly obvious fact,
Quantisation yada yada.
