摘要
介绍了基于DDS设计的频率特性测试仪,整个系统以单片机为控制核心,实现了对被测网络频率特性的测量,用液晶显示器LCD显示幅频特性和相频特性曲线,同时还可打印频响曲线。
The tester for frequency response characteristic based on DDS is introduced, it uses micro controller as the key device, to measure the frequency characteristic of network, then display amplitude and phase frequency characteristic curves with LCD and print them.
