Noise and limitations on sensitivity

2009
There are two major sources of noise in space. One was discovered in 1965 when Arno Penzias and Robert Wilson at Bell Laboratories in New Jersey were calibrating a microwave communication receiver. They were unable to identify a noise that was present at the same signal strength irrespective of the direction in which the antenna was pointed.

NOISE FIGURES, NOISE TEMPERATURES, AND SYSTEM SENSITIVITY

1961
Abstract : The definitions of terms used in systems noise work are presented, as well as general techniques of describing noise power resulting from both the source and the excess noise added by the network under consideration. A unique feature presented is a unified development of 7 noise temperatures encountered in this field, with tables showing the

Differential Sensitivity for Smell: "Noise" at the Nose

Science, 1977
The ability of subjects to resolve differences in concentration of chemicals in the vapor phase by smell rivaled the optimum performance of chromatographs. In some instances, subjects resolved a difference in concentration of only 5 percent. The reported inability of olfaction to register fine differences in intensity seems to be largely a result of ...
