Study on comncuo - based ntc thermistor by complex impedance 熱敏電阻的復阻抗分析
Complex impedance measurement 復阻抗測量
Conventional hybrids used in all existing phone patches can provide good balance at only one frequency into a complex impedance such as telephone line 傳統(tǒng)的混合線路采用所有現(xiàn)行的電話臨時線路技術,只能做到單一頻率的良好平衡進入如電話線的復數(shù)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 復阻抗的熱噪聲僅僅是電阻部分的熱噪聲,因此理想的電容器或電感器雖然有阻抗,但并沒有熱噪聲。
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 結果發(fā)現(xiàn)輝長巖復阻抗的實部隨頻率的增加而減小,而虛部隨頻率增加先增大后減?。幌嘟请S頻率增加而減小。
