RANDOM FLUCTUATION IN AN ELECTRICAL SIGNAL
Noise (telecommunications); Random noise; Line noise; Electrical noise; Noise (physics); Noise (electronic); Noise (signal); Electronic noise; Signal noise; Channel noise; Hiss (electronics); Electronic circuit hiss; Coupled noise; Transit-time noise
<communications> 1. Spurious characters due to electrical noise in a communications link, especially an EIA-232 serial connection. Line noise may be induced by poor connections, interference or crosstalk from other circuits, electrical storms, cosmic rays, or (notionally) birds crapping on the phone wires. 2. Any chunk of data in a file or elsewhere that looks like the results of electrical line noise. 3. Text that is theoretically a readable text or program source but employs syntax so bizarre that it looks like line noise. Yes, there are languages this ugly. The canonical example is TECO, whose input syntax is often said to be indistinguishable from line noise. Other non-WYSIWYG editors, such as Multics "qed" and Unix "ed", in the hands of a real hacker, also qualify easily, as do deliberately obfuscated languages such as INTERCAL.

Brownian noise         
  • A two-dimensional Brownian noise image, generated with a [https://www.mathworks.com/matlabcentral/fileexchange/121108-coloured-noise computer program]
  • A 3D Brownian noise signal, generated with a [https://www.mathworks.com/matlabcentral/fileexchange/121108-coloured-noise computer program], shown here as an animation, where each frame is a 2D slice of the 3D array.
  • Spectrum of Brownian noise, with a slope of –20 dB per decade
THE KIND OF SIGNAL NOISE PRODUCED BY BROWNIAN MOTION
Brown Noise; Brown noise; Red noise; Random walk noise; Red-noise
In science, Brownian noise, also known as Brown noise or red noise, is the type of signal noise produced by Brownian motion, hence its alternative name of random walk noise. The term "Brown noise" does not come from the color, but after Robert Brown, who documented the erratic motion for multiple types of inanimate particles in water.

RANDOM FLUCTUATION IN AN ELECTRICAL SIGNAL
Noise (telecommunications); Random noise; Line noise; Electrical noise; Noise (physics); Noise (electronic); Noise (signal); Electronic noise; Signal noise; Channel noise; Hiss (electronics); Electronic circuit hiss; Coupled noise; Transit-time noise
In electronics, noise is an unwanted disturbance in an electrical signal. Noise generated by electronic devices varies greatly as it is produced by several different effects.

Galactic year

The galactic year, also known as a cosmic year, is the duration of time required for the Sun to orbit once around the center of the Milky Way Galaxy. One galactic year is 230 million Earth years. The Solar System is traveling at an average speed of 230 km/s (828,000 km/h) or 143 mi/s (514,000 mph) within its trajectory around the galactic center, a speed at which an object could circumnavigate the Earth's equator in 2 minutes and 54 seconds; that speed corresponds to approximately 1/1300 of the speed of light.

The galactic year provides a conveniently usable unit for depicting cosmic and geological time periods together. By contrast, a "billion-year" scale does not allow for useful discrimination between geologic events, and a "million-year" scale requires some rather large numbers.
