The software is used by most all Echo Canceller
(EC) manufacturers to simplify the compliance testing of ECs."
As a result, echo cancellers
can be required to have taps covering the entire length of the channel.
rely on sophisticated yet robust algorithms to address divergence, double talk, clipping and annoying changes in background noise.
Ditech Communications Corporation (Nasdaq: DITC) announced its new SX-24 and SX-30, the industry's only echo cancellers
to combine single T1/E1 echo cancellation capability and a wide array of voice enhancement software programs (VQoS) on a single rack-mounted card.
Hands-free operation requires the use of headsets or expensive echo cancellers
Luckily, Digital Subscriber Line technology employs self-adaptive digital filtering to adjust echo cancellers
And, "spamming" has generated a new online defense mechanism: "spam cancellers
." These defenders check news-groups for postings identical or near-identical to the messages they've received and send out a "cancel" message to other users, who then zap your offer before it sees the light of a computer screen.
This will enable OEMs to download proprietary or commercial-off-the-shelf software for functions such as vocoders, echo cancellers
, speech analysis, data and fax modems, encryption, and many others.
Modems used in the high-speed transmission of digital data through telephone channels use adaptive line equalizers and adaptive echo cancellers
. Each adaptive system utilizes a single-neuron neural network.
