IEEE Transactions on Electron Devices, 1994 This survey deals with 1/f noise in homogeneous semiconductor samples. A distinction is made between mobility noise and number noise. It is shown that there always is mobility noise with an a value with a magnitude in the order of 10-4. Damaging the crystal has a strong influence on a, a may increase by orders of magnitude.

Noise Source Predominance Map: a new representation for strategic noise maps
Noise Mapping, 2022 Environmental noise prevention starts from strategic noise maps of main transport infrastructures and agglomerations. Graduated colors are representative of the average noise levels produced in space by each individual source, or the by the overall sum ...
