details about the test vector - Ravi Revankar - Jul 23 4:23:00 2003



Hi,
I need some information about the css (composite
source signal) required for echo canceller testing.
Can I get it free in some URL. If someone has
generated it on his, please give me some information
for generation of the signal.

RAvi

You have to get yourself registered on the ITU-T
website and after that they will allow you to download
a couple of ITU-T standards. You can select the echo
cancellation specs (ITU-T G.168/G.165) etc, and
alongwith which you will get the testvectors if there
is any. --- Ravi Revankar <> wrote:

There are no test vectors for the echo canceller Rec. However, G168
tells how to construct the CSS
