This paper firstly presents two criteria: residual noise energy andsignaldistortion criterion to evaluate the degrees of noise suppression andsignaldistortion.
本文首先提出了客观评价噪声压缩效果的两个指标：残余噪声能量和信号畸变指标。

Based on the features of signals to be measured, the corresponding signal conditioning circuits are designed with the components of ultra-low noiseand low distortion.
