摘要
通过对电子电路的谐振特性的研究,发现谐振电路中的品质因数,其在探讨电路的电压、信号的选频性、电路的储能效率和信号的衰减程度等方面是一个重要的参数。利用PSpice软件对谐振电路的频率扫描仿真分析,更说明了品质因数的大小会影响电路的选频性。结果表明,对于品质因数的意义研究有助于准确理解电子电路中的谐振特性。
Analysis of the resonance characteristics of electronic circuit indicates that the quality factor is a extremely important parameter for exploring the voltage ratio, frequency-selective of signal, energy storage efficiency and the degree of attenuation of signal, etc. Frequency scanning simulation analysis of resonance circuit using Pspice further verifies the influence of quality factor on frequency-selective. The result shows that the study of its significance can help understand accurately the resonance characteristics of electronic circuits.
