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 a new 2-degree-of-freedom control. 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.
