Center clipper, английский
Variable attenuator which is used to eliminate any residual echo left by the echo canceller. a key difference between one canceller and another is the manner in which this center clipper operates. in a high quality canceller, the center clipper will operate very rapidly and smoothly, resulting in no residual echo during double-talk and no clipping of syllables. the center clipper is in essence a level- activated switch. signals above the threshold level are passed unaltered and signals below the threshold are blocked. when speech is present in both directions, the center clipper tends to mutilate the speech signal, adding audible amounts of harmonic and intermodulation distortion. this distortion is often referred to as glitch and sounds remarkably like its name when it occurs. the transmit signal can be totally chopped out if the level of the transmit signal drops below the estimated level of returning echo.
