    • Apparatus for converting numbers between positive and negative radices comprising a plurality of EXCLUSIVE OR logic circuits responsive to the digits of the numbers to be converted, respectively. A plurality of AND logic gates responsive to the digits of the even orders of the numbers, respectively, and a plurality of OR logic gates responsive to the digits of the odd orders of the numbers, respectively, are included. Each AND gate and each EXCLUSIVE OR circuit associated with a particular even order is responsive to the output of the OR gate associated with the odd order preceding the particular even order. Each OR gate and each EXCLUSIVE OR circuit associated with a particular odd order is responsive to the output of the AND gate associated with the even order preceding the particular odd order.
    • 用于分别在正和负辐射之间转换数字的装置,其分别响应于要转换的数字的数字而包括多个独占或逻辑电路。 多个AND逻辑门分别​​响应于数字的偶数位的数字,以及响应于数字的奇数位数的多个OR逻辑门。 与特定偶数阶相关联的每个与门和每个独占或电路响应于与特定偶数阶之前的奇数阶相关联的或门的输出。 与特定奇数阶相关联的每个或门和每个EXCLUSIVE OR电路响应与特定奇数阶之前的偶数阶相关联的与门的输出。
