As we already know that an electrical signal is transmitted through a channel by the help of conductors. So, the electrons present in the conductors move randomly. The random motion of the electrons is the reason for the thermal energy received by the conductor. However, these free electrons are non-uniformly distributed within the conductor. Due t...
Shot noise in a communication channel is the result of random variation in the appearance of electrons and holes at the output side of the device. These random movements are the result of discontinuities in the device which is being used by the system. The shot noise generates sound like several lead shots are striking over a metal plate or tube. I...
Here the name itself is indicating the cause for generation of this type of noise. As it gets generated when the system is composed of multiple paths, and during the flow, the current gets divided in these paths. These are nothing but the result of random variation in the divisions. Due to this reason some devices offer low partition noise while so...
It is also known as low-frequency noise and it occurs because of the variation in the carrier density. Due to this variation or fluctuation, the conductivity of the material gets varied. So, when a direct current is allowed to flow through the conductor then fluctuating voltage drop across in the conductor results in flicker noise voltage. It is to...
It is also known as high-frequency noise. It arises when the charge carriers require comparatively more time to travel from one end to another within the conductor. This effect is called transit time effect. For low-frequency applications, this effect is avoidable but for high-frequency applications the effect is unavoidable. Due to this transit ti...
