i know what is qam and pcm.
i have files witch is recorded as pcm wav file.
i know fax is using qam for modulation/demodulation of digital data to/from analog sygnal.
i know how to get tiff images from the digital data, but i don't know how to connvert this analog signals.
i am parallel connected to the analog phone line witch is using to send/receive faxes.
i am recording this analog signals in vawe/pcm format.
i know how fax protocol is working, but i don't know how modulates digital signals to analog... and how to demodulate analog signals and get digital...
now i have connected with line in cable to the my phone cable. i am sending faxes to another line and recording it's analog signals with sound forge.
i have documentation about qam but i can't get any digits from this vawe files.
i am searching algorithm how to demodulate analog...
from analog to digital(PCM/QAM)
I want to convert analog to digital.
I am recording analog signals in my firm and i want to make a programm witch helps me to decode fax informations.
if you know how to decode this analog signals witch is modulated with PCM/QAM, please help me.
