It appears that Google _isn't_ my friend today (or at least not Alta Vista).
I'm looking for information on what's actually done for sampling on the
PSTN.
Anybody know what is current practice for anti-aliasing filters before
digitizing at 8kHz? Anybody know what the practice was back in the day
when it was all built up out of 44mH inductors?
TIA
