工业电源的工作流程是怎样的?
答:当市电进入电源后,先经过扼流线圈和电容滤波去除高频杂波和干扰信号,然后经过整流和滤波得到高压直流电。接着通过开关电路把直流电转为高频脉动直流电,再送高频开关变压器降压。然后滤除高频交流部分,这样后输出供电脑使用相对纯净的低压直流电。

在时间上和数量上都是离散的物理量称为数字量。把表示数字量的信号叫数字信号。把工作在数字信号下的电子电路叫数字电路。
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,所在为记数。可见,零件数目这个信号无论在时间上还是在数量上都是不连续的,因此他是一个数字信号。小的数量单位就是1个。
