Abstract
There is disclosed an arrangement for removing error signals on a loop conferencing system. A decay circuit is inserted in the conference loop and all signals passing through the decay circuit are reduced by a constant factor. Those signals which are not regenerated by the valid inputs to the loop are reduced to zero within a few cycles.
