sign digit

Based on sign digit negabinary representation, the two step addition and one step subtraction of arbitrary length operands can be performed.

基于符号数字负二进制表达，提出了任意字长操作数的并行两步加法与一步减法。

Several key techniques including real time noise reduction, design of algorithms and sign digit, time allocation for all working parts, and clock synchronizing with a background of high noise are investigated.

研究了实时去噪的几项关键技术、算法和符号位的设计，各部分工作时间分配以及大背景噪声下时钟同步方法。

This result was compatible with the phylogenetic hypothesis. ( 2) Compared to positive numbers, negative numbers had higher activation thresholds. ( 3) The sign and the digit of negative numbers can be processed independently, which supported the separate processing view.

与正数相比，负数数量表征的激活阈限更高。（3）负数的符号和数字部分各自独立进行加工，这一结果支持分离加工的观点。

The third experiment was aimed at investigating the processing of the sign and digit in negative numbers by adopting the asynchronous display method.

同时，实验三还引入符号与数字分时呈现的技术，对负数的符号与数字加工的方式（整体加工或分离加工）进行探讨。

The redundant sign digit error correction makes it possible to use dynamic comparator for power reduction.

由于运用了冗余数字校正技术，可以采用低功耗的动态比较器。
