在系统的制造和控制、测量等方面,数字技术、计算技术日益引起人们的重视。然而,这门技术虽然重要,但也不应造成一股忽视模拟技术的倾向。模拟技术与数字技术相比也是决不可慢待的。在物理现象的分析和系统的设计等方面,模拟技术是不可缺少的技术。为了加深对模拟技术的理解,使模拟技术在适于采用的领域得以充分推广,从而取得和数字技术相适应的发展,本文说明一下基本模拟运算回 In the system manufacturing and control, measurement, etc., digital technology, computing technology has drawn increasing attention. However, this technique, while important, should not create a tendency to ignore analog techniques. Simulation technology and digital technology is also not to be slow compared. In the analysis of physical phenomena and system design, simulation technology is an indispensable technology. In order to deepen the understanding of analog technology, so that analog technology can be fully applied in the field of promotion, and thus obtain the appropriate digital technology development, this article describes the basic analog computing back
