摘　　要：谐振法是测量RLC参数的三大方法之一,要解决的主要问题是频率稳定性及测试时间较长的问题,以DDS作为激励信号,能较好地满足谐振法高精度测量的要求。文中硬件给出了具体电路参数,软件给出了相应软件流程,总结了提高性能的方法。Resonance method is a method of measuring the parameters of RLC. However, how to keep frequency stability and shorten the measuring time are two major problems and must be solved in this method. In this paper, a high performance RLC iusmanent design based on DDS is introduced. The requirement of high precision is satisfied perfectly by employing DDS. The circuit parameters of hardware and corresponding software flow of system are described in detail, and the methods of improving performance are snmmarizod as well.
