| 摘 要： | 本文提出了一种舍入量化器统计量化特性线性化的概念。根据这一概念找到了一种抑制数字滤波器极限环的方法。该方法能抑制一阶、二阶数字滤波器中所有极限环,并且滤波器输出不存在剩余噪声。本文还提出了一种求极限环平均抑制时间的计算方法,计算结果与实验数据相符。

| Abstract: | This paper proposes a linearization conception of the statistical quantization characteristic of roundoff quantizer. According to this conception the method of limit cycle suppression in the first-and second-order digital filters is found. All the limit cycles in digital filters can be suppressed by the use of this method and no remaining noise exists in the filter output. The calculation method of finding the limit cycle suppression time is proposed also and the calculation results are consistent with those obtained from experiments. |
