In particular, Electronic noise is inherent in physics, and central to thermodynamics.
FactSnippet No. 644,039 |
Electronic noise is a common component of noise in signal processing.
FactSnippet No. 644,040 |
In communication systems, Electronic noise is an error or undesired random disturbance of a useful information signal in a communication channel.
FactSnippet No. 644,041 |
The Electronic noise is a summation of unwanted or disturbing energy from natural and sometimes man-made sources.
FactSnippet No. 644,042 |
Different types of Electronic noise are generated by different devices and different processes.

Johnson–Nyquist Electronic noise is unavoidable, and generated by the random thermal motion of charge carriers, inside an electrical conductor, which happens regardless of any applied voltage.
FactSnippet No. 644,044 |
Thermal Electronic noise is approximately white, meaning that its power spectral density is nearly equal throughout the frequency spectrum.
FactSnippet No. 644,045 |
Where current divides between two paths, Electronic noise occurs as a result of random fluctuations that occur during this division.
FactSnippet No. 644,046 |
Thermal Electronic noise can be reduced by cooling of circuits - this is typically only employed in high accuracy high value applications such as radio telescopes.
FactSnippet No. 644,047 |
The spectral distribution of Electronic noise can vary with frequency, so its power density is measured in watts per hertz .
