PCM (Pulse Code Modulation)
digital certificate A code used to authenticatethe source of a file or document or to identify and authenticate
No, Pulse Code Modulation is a communication method used to carry digital data but is not part of any analog to digital conversion. PCM is often used to carry audio data as a digital stream and therefore is the encoding used as the signal is first converted to a digital format.
The testing method used to perform a breast exam is a mammogram.
The activation code is the code that is found on the box or email (digital downloads) of the installer program. Each code can only be used by the disc that came with it. No other person can use that code.
I believe that each disc has it's own copy code which would've been included in the disc case. If you bought it new and did not get a code you should either return the disc or contact Fox. If you bought it used you need to talk to the seller. The previous owner may have "used up" the digital copy.
