摘要
对于由至少一个电感器和一个电容器组成的二端网络,当二端网络的输入阻抗是纯电阻性时,电路发生了谐振。当二端网络外加一个幅度恒定的正弦电流源,电压响应正比于电路的输入阻抗。文章证实了并联谐振电路中电压响应的最大值不是发生在谐振频率处,而是发生在谐振频率附近。
In a two-terminal electrical network containing at least one inductor and one capacitor,resonance is defined as the condition which exists when the input impedance of the network is purely resistive.If we assume a constant-amplitude sinusoidal current source,the voltage response is proportional to the input impedance.It proves that the maximum value of the response about parallel resonance is reached in the vicinity of the resonant frequency,not occurred exactly at the resonant frequency.
