I know that MP3 is lossy. All I am asking is if the audio input can
*physically* (due to transmission) match the audio heard over an FM
receiver exactly. Just assume that you have the highest quality CD
source media, CD player, FM transmitter, Antenna, FM receiver, and
Speakers -- and all that is left to degrade the signal is the
modulation of the input over the FM channel -- will the input match the
output??? This is what I want to know. I mean, the act of taking a
100% clean CD audio input -- piping it over FM (with no constraints but
the theoretical math involved in modulating the signal over say 108
MHz) -- will it end up 100% clean on the other side? I don't care
about any other factors. Mathematically, does the transmission of CD
audio input via FM have the effective output of about 256 Kbps MP3
lossy audio on the receiving end? Is it a degrading function (forget
the very low and very high frequencies)? Wow, I must have reworded
this about 50 times now...lol Forgive my naivety!
