Abstract

To decrease the quantization noise, various 1-bit digital filters are shown. In this paper, we propose a design method of 1-bit digital filter using an Approximate 2-Degree-of-Freedom control. The filter become very simple and the stability of the filter is easy to attain, So the dynamic range of filter is more wide than usual filters. This design method is applied to a high-pass filter, a low-pass filter and a equalizer. These filters are implemented on DSP, and the performance is verified by the experiment.
