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.
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 :
The research group has also investigated and developed noise models for polysilicon emitter bipolar transistors, lateral pnp bipolar transistors and SiGe heterojunction bipolar transistors. One of the contributions of the research group is the demonstration of random telegraph signal (RTS) noise as a non-destructive characterization and ...
The logic values are represented by multi-dimensional "vectors" (orthogonal functions) and their superposition, where the orthogonal basis vectors are independent noises. By the proper combination (products or set-theoretical products) of basis-noises, which are called noise-bit, a logic hyperspace can be constructed with D(N) = 2 N number of dimensions, where N is the number of noise-bits.
Almost every technique and device for signal processing has some connection to noise. Some random examples are: Noise shaping; Antenna analyzer or noise bridge, used to measure the efficiency of antennas; Noise gate; Noise generator, a circuit that produces a random electrical signal; Radio noise source used to calibrate radiotelescopes

Morgan Ortagus, a Donald Trump critic turned supporter, will serve as his deputy special envoy for Middle East peace.
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.
