| Abstract: | The principle of floating-point A/D conversion, practical circuit and design of pile detector are introduced in this paper. The conversion method is of large dynamic range, large signal-noise rate, and can compress the signals with large variation scale. The method could be well used in designing acquisition sys-tems of signal data with large variation. |
