∑-Δ调制器和∑-Δ调制方法
摘要：
一种∑-Δ调制器，包括：包括带可变磁滞的量化器并接收输入信号以执行所需调制操作的调制器模块。接收与所述输入信号相关的信号并对所需磁滞控制信息制表以降低所述调制器模块的跃变速率的非线性映射模块。
摘要（英）：

A sigma delta modulator includes a modulator module that includes a quantizer with variable hysteresis, which receives an input signal to perform necessary modulation operations. A non-linear mappingmodule receives a signal associated with said input signal and tabulates the necessary hysteresis control information so as to reduce the transition rate of the modulator module.
