All real voltage and current sources contain an internal resistance; therefore, they exhibit Johnson noise.

所有真实的电压源和电流源都具有内阻, 所以它们都表现出约翰逊噪声.

互联网

All voltage sources have internal resistance, so all voltage sources develop Johnson noise.

所有的电压源都具有内阻, 所以所有的电压源都会产生约翰逊噪声.

The fundamental limit to measurement is Johnson noise in the source resistance.

对测量的基本限制是源电阻中的约翰逊噪声.

互联网

Johnson noise is purely an effect of resistance.

热噪声纯粹是电阻的效应.
