- Noise refers to any unwanted electrical or electromagnetic interference that disrupts the transmission of signals over communication channels. This interference can degrade the quality of data transfer, leading to errors and loss of information, which is critical when evaluating physical media and transmission characteristics.

Electronic noise is also known as “background noise,”. It is one of the most common type of noise that is caused by the random movements of electrons in electronic components like transistors, diodes, and amplifiers. It is an unwanted disturbance in an electrical signal that can degrade the quality of the signal, cause distortion in the signal, and...
Thermal noise is another common type of noise caused by the random movements of electrons in network cables or conductors. This random movement generates a small amount of electrical noise, which can accumulate and distort the signal being transmitted. In essence, it is a noise that occur due to heat temperature as electrons move along a conductor....
Crosstalk is a type of noise which is caused by electromagnetic interference (EMI) between adjacent network cables or conductors. When two or more cables are placed close to each other, the electrical signals in one cable can induce an unwanted signal in the adjacent cable. This unwanted signal can cause distortion and reduce the quality of the ori...
Impulse noise consists of sudden, short-duration bursts of interference. It can be caused by external factors like electrical surges, lightning strikes, or electromagnetic pulses. These sudden changes can overload the network and cause distortion or even damage to the equipment. It can be reduced by using surge protectors and other protective measu...
Intermodulation noise is caused when two or more signals with different frequencies mix together and create new frequencies that can interfere with or distort the original signals. The interaction between multiple signal occurs mostly in a nonlinear devices or mediums. It can be reduced by using filters and other signal processing techniques that c...
This type of noise is caused due to the time it takes for electrons to travel through electronic components, which can cause delays and distortions in the signal. It is more common in high-frequency systems and can be reduced by using high-quality components with short transit times.
Shot noise is caused by the random fluctuations in the current or voltage that occur due to the discrete nature of electrons. Shot noise is most noticeable in low-level signals. It arises due to the quantized nature of particles, such as electrons or photons, and leads to statistical variations in the signal. It is more commonly found in high-speed...
Gaussian noise is a type of noise that is caused by random variations in the signal amplitude that follow a normal distribution. This type of noise is also known as “white noise” and has a flat spectrum. It is often used as a model for other types of noise. It is a common type of noise in wireless networks and can be caused by factors like atmosphe...

Aug 10, 2019 · Noise refers to any external and unwanted information that interferes with a transmission signal. Noise can diminish transmission strength and disturb overall communication efficiency. In communications, noise can be created by radio waves, power lines, lightning and bad connections.
Definition: Noise in a communication system is basically undesirable or unwanted signals that get randomly added to the actual information carrying signal. Resultantly, causes disturbances in the original signal being transmitted from an end to another.
