  2. Burst noise - Wikipedia

    en.wikipedia.org/wiki/Burst_noise

    Burst noise is a type of electronic noise that occurs in semiconductors and ultra-thin gate oxide films. [1] It is also called random telegraph noise ( RTN ), popcorn noise , impulse noise , bi-stable noise , or random telegraph signal ( RTS ) noise.

  3. Telegraph process - Wikipedia

    en.wikipedia.org/wiki/Telegraph_process

    It models burst noise (also called popcorn noise or random telegraph signal). If the two possible values that a random variable can take are c 1 {\displaystyle c_{1}} and c 2 {\displaystyle c_{2}} , then the process can be described by the following master equations :

  4. Noise generator - Wikipedia

    en.wikipedia.org/wiki/Noise_generator

    Zener diode based noise source. A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters. Noise generators are also used for generating random numbers. [1]

  5. Noise (electronics) - Wikipedia

    en.wikipedia.org/wiki/Noise_(electronics)

    Telecommunication systems strive to increase the ratio of signal level to noise level in order to effectively transfer data. Noise in telecommunication systems is a product of both internal and external sources to the system. Noise is a random process, characterized by stochastic properties such as its variance, distribution, and spectral density.

  6. White noise - Wikipedia

    en.wikipedia.org/wiki/White_noise

    In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. [1] The term is used with this or similar meanings in many scientific and technical disciplines, including physics , acoustical engineering , telecommunications , and statistical forecasting .

  7. Quadruplex telegraph - Wikipedia

    en.wikipedia.org/wiki/Quadruplex_telegraph

    At the remote end, the sent current flows through both solenoids in the same direction and into the termination load. Since current flows the same way in both solenoids the remote signal relay is activated by this local key. For the Diplex, a different trick is used. To send two messages simultaneously, one has two independent local telegraph keys.

  8. Signal generator - Wikipedia

    en.wikipedia.org/wiki/Signal_generator

    A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.

  9. Worley noise - Wikipedia

    en.wikipedia.org/wiki/Worley_noise

    Worley noise, also called Voronoi noise and cellular noise, is a noise function introduced by Steven Worley in 1996. Worley noise is an extension of the Voronoi diagram that outputs a real value at a given coordinate that corresponds to the Distance of the nth nearest seed (usually n=1) and the seeds are distributed evenly through the region.
