This circuit can be widely used in input amplitude discriminator and anticoincidence test. 该反符合电路主要用于输入信号幅度甄别和反符合测量。
The gradient algorism is developed to extract the defect signal.The variation of signal amplitude and gradient is used as the standards of the defect assessment. 提出了提取缺陷信号特征的梯度算法，用信号幅度和梯度值的变化作为缺陷估计标准。
