johnson noise 中文意思是什麼
johnson noise
解釋
【無線電】約翰遜噪聲,熱(激)噪聲。-
Johnson noise is purely an effect of resistance
熱噪聲純粹是電阻的效應。 -
Johnson noise voltage
熱噪聲電壓 -
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,但並沒有熱噪聲。 -
A final " imperfection " of resistors is an inconvenience but cannot properly be regarded as an imperfection as it is a fundamental property of all resistors : thermal or johnson noise
關于電阻的非理想特性,最後一項內容是熱噪聲,也稱為約翰遜噪聲。其實這並不能稱為完全意義上的非理想特性,它是電阻的固有性質,任何電阻器都不例外。
