Study on comncuo - based ntc thermistor by complex impedance 热敏电阻的复阻抗分析
Complex impedance measurement 复阻抗测量
Conventional hybrids used in all existing phone patches can provide good balance at only one frequency into a complex impedance such as telephone line 传统的混合线路采用所有现行的电话临时线路技术,只能做到单一频率的良好平衡进入如电话线的复数阻抗中。
The johnson noise of complex impedances consists only of the johnson noise of the resistive part of the impedance , so pure capacitance or inductance does not have johnson noise , even though it has an impedance 复阻抗的热噪声仅仅是电阻部分的热噪声,因此理想的电容器或电感器虽然有阻抗,但并没有热噪声。
The real part of the complex impedance decreases with frequency ; the imaginary part of the complex impedance increases with frequency to the maximum , and then decreases with frequency ; and phase angle decreases with frequency increasing 结果发现辉长岩复阻抗的实部随频率的增加而减小,而虚部随频率增加先增大后减小;相角随频率增加而减小。
