Does anyone know if digital signals (e.g. WIFI) are sent by
frequency modulation or amplitude modulation or something else? I
read in Wikipedia something about the phase difference between two
or more carrier frequencies encoding the ones and zeros but that
sounds to me like basically FM. I know the transmission frequencies
are much higher than AM or FM which makes sense if you want to send
lots of information. I need some simple (simplistic) explanation to
follow a simple explanation of AM and FM for my intro class.
