数字-模拟转换器虽然可将数字量转换为与其对应的模拟量,但它并不能实施模拟量输出通道的所有功能。本文所介绍的增量控制模式则是一种能实现手/自动双向无扰动切换的控制模式。本文论述了增量控制模式与无扰动切换之关系,提供了实施这种控制模式在硬件设计上的一些构思和考虑。 Digital-to-Analog Converters Although it is possible to convert a digital quantity to an analog quantity that corresponds to it, it does not perform all the functions of an analog output channel. The incremental control mode described in this article is a control mode that enables hands-free, bi-directional, bumpless switching. This paper discusses the relationship between incremental control mode and bumpless switching, and provides some ideas and considerations in hardware design for implementing this control mode.
