MELP vocoders utilize mixed pulse and noise as the excitation to elimate the buzzes in traditional LPC vocoders, and add a jitter voicing state to overcome the tonal noise.
Add the workpiece fixed in the coil, coil discharge at the moment have a damping pulse magnetic field decay, so that the loss of magnetic parts.
工件放入线圈中不动，线圈在放电瞬间产生脉冲阻尼衰减磁场，使工件失去磁性。

In that case we would never add up all the parts of the signal at the same time, and would never see the clear spike that tells us that a pulse from outer space has been received.
