一个经典的宽带多位sigma delta调制器设计，较为好用-More than a classic sigma delta modulator broadband design, the more useful

通过MATLAB对过采样sigma-delta调制器进行仿真的设计方案，采用多级级联结构，有效减少运算量和硬件开销。-By MATLAB on the over-sampling sigma-delta modulator design simulation, using multi-stage cascade structure, effectively reduce the computational complexity and hardware overhead.
