为便于与微处理机或数字显示仪表接口,目前常用的检测方法是通过A/D转换进行的。为此需要预先将信号进行放大。数字化测量技术则强调尽可能直接进行数字转换,从而省去放大部分和A/D转换部分,或用D/A来代替A/D,这样能够避免由此带来的误差,并减少检测装置的成本。本文详细介绍了若干数字化测量的实现技术。图5幅参3
In order to facilitate the interface with the microprocessor or the digital display instrument, the commonly used detection method is through A / D conversion. For this purpose, the signal needs to be amplified in advance. Digital measurement techniques emphasize direct digital conversion as much as possible, eliminating the need for amplification and A / D conversion, or replacing A / D with D / A, which avoids the resulting errors and reduces the number of cost. This article describes in detail a number of digital measurement technology. Figure 5 Senate parameters 3
