Adaptive digital filters with variable step-size may become unstable when their weights are automatically adjusted with input signal and noise.

变步长自适应数字滤波器的权值随信号和噪声的变化自动调整时可能出现不稳定。

Because the noise sources have different values during each conversion, the ADC will most like produce different digital results for a fixed input.

因为噪声源在每个转换期间具有不同的值，因此adc将很可能对于固定的输入而产生不同的数字结果。
