Bode’s noise theorem is an efficient way of determining the total noise in passive, linear RLC networks. This theorem has been traditionally derived in the frequency-domain using contour integration. We present an alternative (and more intuitive) derivation of Bode’s theorem. Our technique works in the time-domain and exploits energy conservation. Finally, we apply our technique to determine the autocorrelation function of the noise at the output of the network.
