Linear ODE's for describing sigma-delta-modulators, filter design and error estimations. - In: New trends in difference equations, (2002), S. 159-171

A Sigma-Delta Modulator of order 2 is approximated by a differential equation of first order. An error estimation with respect to the real time behavior of order O(1/m^2) is given, where m is the number of bits used for the filtering. A filter with this error bound related to the moving mean value of the input signal is proposed.
