本文介绍的简易模数转换器,可以将模拟量转换成十几个数字脉冲,适用于机械加工工业。例如近年来国际上新兴的尺寸自动控制技术,是将被测工件尺寸与标准工件尺寸(取公差中点值)两者所代表的模拟电压相比较,将它们的差(有正负)放大后转换成数字脉冲,然后反馈到计算机中对被测工件进行修正。一、方框图简易模数转换器由阶梯波发生器、射极跟随器Ⅰ、Ⅱ、限幅器、正负微分电路、一周期 This article describes the simple analog-to-digital converter, analog to digital conversion can be a dozen, suitable for the machining industry. For example, in recent years, internationally-developed automatic dimensioning technology compares the measured workpiece size with the analog voltage represented by the standard workpiece size (taking the tolerance midpoint value), and amplifies the difference (plus or minus) Converted to digital pulse, and then fed back to the computer to be tested workpiece correction. First, the block diagram Simple analog-to-digital converter from the ladder wave generator, emitter follower Ⅰ, Ⅱ, limiter, positive and negative differential circuit, a cycle
