A decade or so ago, I designed a simple circuit that included a quad optoisolator arranged in a full-wave analog-multiplier bridge (Figure 1).
大约十年,计了一个简单电路,包按全波模拟乘法器电的四个光耦(图1)。

Notable among these devices was the Step Reckoner, built by German polymath Gottfried Leibniz in 1694.
在这些器中,莱布尼茨乘法器格外着名 它由德国博特弗里德·莱布尼茨于1694年建造。
With some clever mechanical tricks, the Step Reckoner was also able to multiply and divide numbers.
利用一些智的械技巧 莱布尼茨乘法器也能够乘数和除数。
Unlike the Difference Engine, Step Reckoner and all other computational devices before it - the Analytical Engine was a " general purpose computer" .
不,以及莱布尼茨乘法器和所有其他以前的计算设备-析是一台" 通用计算" 。
The Step Reckoner was able to do this in an automated way, and was the first machine that could do all four of these operations.
莱布尼茨乘法器可以自动实现这种操作而且它也是第一台能做到加减乘除四种运算的器。
