摘要
介绍了一种采用Chirp信号作为激励信号的虚拟频谱分析仪的设计原理,并利用图形化编程工具LabVIEW 6.1实现了此种虚拟频谱分析.实验测试结果表明:采用LabVIEW 6.1所设计的以Chirp作为激励信号的虚拟频谱分析仪具有较好的测量效果,可比传统频谱分析仪更快捷地测量出系统的幅频特性和相频特性.
The paper presents the design principle of a kind of visual spectrum analyst,which adopts the Chirp signal as excitation.The spectrum analyst is designed by means of the graphical program tool LabVIEW 6.1.Its test indicates that the analyst is more quick and convenient than traditional ones in the measurement of the frequency-amplitude and phase frequency characteristics.
