In terms of given manufacture process planning, signal-noiseratio (SNR) was employed to scale quality loss of each process.
针对加工工艺规划,提出采用信噪比衡量各道工序对产品质量损失的影响。

But to the CW pulse signal with changing carrier wave frequency, common filter cannot achieve narrowband filter, whereas broadband filter cannot reach the request of the signal-noiseratio.
