摘要

本文将σ - δ调制器系数的计算作为数字滤波器的设计问题。传递函数系数的数值计算使用切比雪夫或巴特沃斯数字滤波器设计可用的程序。利用离散电路的矩阵模型，得到了任意结构的调制器传递函数系数与σ - δ调制器结构系数的符号表达式。

Design of sigma-delta modulators of arbitrary topology

Calculation of sigma-delta modulator coefficients is presented in this work as the problem of digital filter design. Numerical values of a transfer function coefficients are calculated using available procedures for Chebyshev or Butterworth digital filters design. Symbolic expressions linking transfer function coefficients with sigma-delta modulator structure coefficients are obtained for a modulator of arbitrary structure using matrix model of corresponding discrete circuit.
