利用NI ELVIS提供的函数信号发生器作为电路的激励信号，在正弦交变信号的作用下，RLC 电路元件在电路中的抗流作用与信号的频率有关。RLC阻抗特性测试实验验证了电阻、感抗、容抗与频率的关系。

-Use NI ELVIS provides signal generator as a function of the excitation signal circuit under sinusoidal alternating signal role, RLC circuit elements in the circuit choke function and signal frequency. RLC impedance characteristics of the test results show the relationship between the resistance, inductance, capacitance and frequency.
