This question is for Electronics Engineers/Experts: Can someone point
me to a schematic/application note that demonstrates Audio Isolation
using Opto-Couplers (instead of audio isolation transformers). I have
seen/used circuits that do audio isolation using regular opto-couplers
and not the expensive linear opto couplers. I need to know this for
computer telephony application. I would appreciate your help and
expert advise.
Thanks in advance.
