modem is modulator demodulator
what it does is turn the on off digital signal to something a transmission line can deal with
square waves have lots of harmonics
square waves down a long wire come out as sine waves
one of the simplest methods was FSK frequency shift keying
a 0 is 3500Hz a 1 4900hz sine wave
this is 5:7 ratio fits in the clearest bandwidth of the phone line
the first harmonic where there are coincidences that cant be told apart
will be 35x or 24,500 hz and a voice quality phone line just wont pass it
