{synonym}

Unwanted stochastic fluctuations of <voltage> or <electric current>. Contributions include <thermal noise>, <shot noise>, and resistance fluctuations under bias; their physical origins and dependence on <frequency> need not be identical. A <low-pass filter> attenuates the high-<frequency> part of such fluctuations along with any high-<frequency> signal.
