We discuss a realization method of basic 1-bit signal processing based on Delta-Sigma modulation in this paper. Additionally, we show the characteristics of basic 1-bit processor and an effective design method from the view point of SNR. As the application of the 1-bit signal processing, we proposed a realization method of high-order filters based on Delta-Sigma modulation. We applied the effective design method to decide coefficients of a 4th-order butterworth low pass filter. We show that the filter designed by using the proposed method achieves the highest SNR.
