Subject: 60Hz Synchronous sampling?

Hey all.

I'm trying to get my ducks in a row for my first LP station with computer
logging, and I'm pulling my hair out trying to find an old piece of data.
Could someone please help?  Where have I heard of a sampling rate of 60Hz
(or 30Hz?) which was synchronous and zero-crossing-locked with line
frequency to allow elimination of 60Hz and aliases without multiple-pole
filters?  I think I'd like to replicate this bit of Kung-Fu in my design.
Did I just make this up or did Larry or someone publish an article like
that?

Thanks in advance,
Eric Guinn, AC4LS
