第 3 章 模拟测量方法
DESCRIPTION
第 3 章 模拟测量方法. 第 3 章 模拟测量方法. 学习辅导 内容. 从信号的特征讲，分为模拟信号和数字信号。 模拟信号是其幅度随时间作连续变化的信号。 无论是何种电参数，只要他属于模拟范畴，就要采用模拟测量方法进行测量。或者不完全属于模拟量，只要采取某种技术措施和手段将其变换成模拟量，就可以采用模拟测量方法进行测量。前提是在变换过程中尽可能减小误差，即使产生误差也不能降低测量精度。模拟测量有多种多样，不管使用何种模拟测量方法进行测量，被测量必须是模拟信号。. 一、本章需要掌握的内容. - PowerPoint PPT PresentationTRANSCRIPT
