Well, my goal was to somehow receive QM video signal on a
frequency-modulated ULF [radio-frequency between 300 and 3,000 KHz]
carrier -- in which the QM uses only 1 baud but shoves as many
bits-per-symbol mathematically possible while setting the maximum
voltage of the discrete states low enough not to cause any harm to
anyone or anything [including the equipment itself] -- and with as many
discrete states [between the highest and lowest voltage] as
mathematically-possible. Unfortunately, reality does not want me doing
this and reality always has the last word as to what does and what
doesn’t occur.
Anyways, my next question. Is it possible to split the symbol of a 1
baud, 8-bit-per-symbol signal into 8 bits? I.e. in this case, a single
symbol would be split into 8 different parts each carrying one of the
bits. Is this possible? If so, would this be of any assistance to me?
