  2. 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 :

  3. Burst noise - Wikipedia

    en.wikipedia.org/wiki/Burst_noise

    It is also called random telegraph noise (RTN), popcorn noise, impulse noise, bi-stable noise, or random telegraph signal (RTS) noise. It consists of sudden step-like transitions between two or more discrete voltage or current levels, as high as several hundred microvolts , at random and unpredictable times.

  4. Telecommunications - Wikipedia

    en.wikipedia.org/wiki/Telecommunications

    The broadcast signal can be either analogue (signal is varied continuously with respect to the information) or digital (information is encoded as a set of discrete values). [ 41 ] [ 83 ] The broadcast media industry is at a critical turning point in its development, with many countries moving from analogue to digital broadcasts.

  5. Telegrapher's equations - Wikipedia

    en.wikipedia.org/wiki/Telegrapher's_equations

    The telegrapher's equations (or just telegraph equations) are a set of two coupled, linear equations that predict the voltage and current distributions on a linear electrical transmission line. The equations are important because they allow transmission lines to be analyzed using circuit theory . [ 1 ]

  6. Wireless telegraphy - Wikipedia

    en.wikipedia.org/wiki/Wireless_telegraphy

    Wireless telegraphy or radiotelegraphy, commonly called CW (continuous wave), ICW (interrupted continuous wave) transmission, or on-off keying, and designated by the International Telecommunication Union as emission type A1A or A2A, is a radio communication method.

  7. Pseudorandom binary sequence - Wikipedia

    en.wikipedia.org/wiki/Pseudorandom_binary_sequence

    In contrast, truly random sequence sources, such as sequences generated by radioactive decay or by white noise, are infinite (no pre-determined end or cycle-period). However, as a result of this predictability, PRBS signals can be used as reproducible patterns (for example, signals used in testing telecommunications signal paths).

  9. Array processing - Wikipedia

    en.wikipedia.org/wiki/Array_processing

    Beamforming is a signal processing techniques that produce summed array beams from a direction of interest – used basically in directional signal transmission or reception- the basic idea is to combine elements in a phased array such that some signals experience destructive inference and other experience constructive inference.
