This paper firstly presents two criteria: residual noise energy and signal distortion criterion to evaluate the degrees of noise suppression and signal distortion.
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 noise and low distortion.
根据待测信号的特点,选用超低噪声、低漂移元器件,设计了相应的信号调理电路。
