Abstract
When two uncorrelated thermal noise sources with matched intensities are coupled to the inputs of two-channel noise measurement system, the cross-spectral density of output voltage fluctuations becomes anomalously low, provided the measurement time is long enough. Results of experimental observations of such effect along with its theoretical explanation are presented.
