The project will develop a bandpass sigma-delta analog-to-digital converter for digital audio broadcasting system in three years. In the first year, we had finished the system simulation for IF receiver using conventional high speed ADC and bandpass sigma-delta ADC, respectively. We also had done the analysis and design of high-order bandpass sigma-delta modulator structure. In this year, we have developed a coefficient synthesis method for high order bandpass sigma-delta modulator using high order filter transfer functions (inverse Chebyshev bandreject filter function).

In this chapter, we compare the two different points of the quality economic benefits. We not only establish the econometric model from the traditional viewpoint, but also deduce the econometric model to evaluate the economic benefits of Six Sigma base on the Quality Engineering and Loss Function of Taguchi. Our research has proved that the excess cost decreased quadratically by the increasing of the sigma level.
