  • RLC-Series-resonance-characteristics
    用实验方法测试RLC串联谐振电路的幅频特性曲线。当正弦交流信号的频率f改变时,电路的感抗、容抗随之而变.取电路电压U0作为响应,当输入电压Ui幅值维持不变时,在不同信号频率的激励下,测出U0之值,用LabVIEW程序完成频谱分析和滤波,变换等信号处理,即可测出RLC串联电路的谐振频率,(Amplitude-frequency characteristics experimentally tested RLC series resonant circuit curve. When changing the frequency f of the sinusoidal AC signal, the circuit inductance, capacitance change with Take circuit voltage U0 as a response when the amplitude of the input voltage Ui unchanged, signals at different excitation frequencies, the measured value U0, the process is complete spectrum analysis using LabVIEW and filtering, transform signal processing, can be measured RLC series circuit resonant frequency,)
