逻辑代数基础(中文4400字,英文2900字)
在观察自然界中形形色色的物理量时不难发现,尽管它们的性质名异,但就其变化规律的特点而言,不外乎两大类,
其中一类物理量的变化莫测在时间上和数量级上都江堰市是离散的.也就是说,它们的变化在时间上是不连续的,总是发生在一系列离散的瞬间.同时,它们的数值大小和每次的增减变化都是某一个最小数量单位的整数倍,而小于这个最小数量单位的数值没有任何物理意义.这一类物理量叫做数字量,把表示数字量的信号叫做数字信号,并且把子作在数字信号下的电子电路叫做数字电路.
例如,用电子电路记录从自动生产线上输出的零件数目时,每送出一个零件便给电子电路一个信号,使之记1,而平时没有零件送出时加给电子电路的信号是0,所以它是一个数字信号.最的数量单位就是1个.
原文
Logical algebra foundation
While observing kinds of physical quantity in nature,base on the changing regulation It can be easily find those all besides two main species although their character is quite different from each other.
A kind of physical quality is long-lost on time and numeric Classes.It also can be say that their transformation is discontinuous on time,It always taking place in a series of long-lost moment.Meanwhile their numeric size and every increase or decrease divertion is all the integral double to an least numeric unit,however a numeric less than the least one will not have any physical meaning.This amount of physics is called the numeral quantity, called the signal which express numeric quality for numeric signal.besides called electrical circuit under numeric singal for numeric circuit.
