Hi,
This is not a real SI topic, but I need your analog expertise about the
way to generate echo in a voice traffic.
We need to test an Echo Cancellation module on our board and I would like
to know if I could generate echo without using heavy and expensive
specific test equipment.
Is there a simple "analog" method to perform such an echo on voice with
maybe just a passive network (to simulate an impedance mismatch) or long
cable simulator or other ... ?
Has anyone of you already performed this kind of test?
Thank you,
Regards,
Jean-Pierre
