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.

MELP声码器采用混合脉冲和噪声激励解决了经典LPC的嗡嗡声的问题； 引入了抖动浊音状态以克服音调噪声；

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.

这样的话我们就不能把信号的所有部分都结合起来，也就看不到外太空脉冲那明显的尖峰了。
