The application of single-bit digital signal processing to mechanical control system has already been proposed by the authors. Multi-bit A/D converter has been improved to the high level. But it is difficult to make more high resolution A/D by latest semiconductor technologies. There is single-bit digital signal which is generated by a delta-sigma modulator. Single-bit digital signal has small quantized error around low frequency. Then with this single-bit digital signal processing, high resolution on controlling such a narrow band width mechanical system will be realized. In this paper, resolution of analog, multi-bit and single-bit control systems are estimated with simulation. According to simulations' results, single-bit control system has higher resolution than multi-bit system in the condition of equal bit rate.
