摘要
介绍基于虚拟仪器的四种频率特性测试方法,简述实现各种方法的关键,并比较它们的优缺点;与此同时,阐述虚拟仪器环境下信号产生与数据采集的考虑,并对使用的若干数据处理算法作了说明。
This paper presents four frequency characteristics test methods based on virtual instruments, shows the key points of the implementation of the methods, and discusses the advantages and disadvantages of each method. And the signal generation and data acquisition in virtual instruments environment are carefully thought, several useful data and signal process algorithm applied in experiments are illuminated.
