Thermal noise occurs in all transmission media and
all communication equipment, including passive devices. It arises from random
electron motion and is characterized by a uniform distribution of energy over the
frequency spectrum with a Gaussian distribution of levels.
Noise. Impulse noise is noncontinuous, consisting of irregular
pulses or noise "spikes" of short duration, broad spectral density, and relatively
high amplitude.
What else can I help you with?
1 Which type of noise is most difficult to remove from digital signal?
Impulse Noise is the a noncontinuous noise and one of the the most difficult errors to detect because it occurs randomly. Like a lighting strike, the severity of the static across the radio could be so severe that you couldn't hear the music or like a vinyl record with a scratch, the pops and clicks associated with the hitting the scratch making the sound at that exact moment unrecoverable. Typically though, the impulse noise is an analog burst of energy.
How do you calculate the power of white noise?
To calculate the power of white noise, you can use the formula for power, which is the mean of the squared values of the signal. For a white noise signal represented as ( x(t) ), the power ( P ) can be calculated using ( P = \frac{1}{T} \int_0^T x^2(t) dt ), where ( T ) is the duration of the observation. Since white noise has a constant power spectral density, its power is generally equal to the variance of the noise signal. In discrete terms, if you have a sample of white noise, the power can be approximated as the average of the squared samples.
In an amp What is better high or low signal to noise ratio?
Signal to noise ratio is the difference between the noise floor and the reference level.
Impulse refers to both force and?
Impulse refers to both force and time....... Impulse=(the change in Force)*(time) OR Impulse=the change in Momentum
What is effect of noise on digital communication system?
it will affect the output of a receiver only if it falls within the passband.in that case,the carrier and noise voltage will mix and the difference frequency,if audible,will interfere with the reception of the wanted signal..
What is impulse noise in an image?
Impulse noise is a short duration noise.
What is the Name and briefly describe four types of noise?
1. White noise 2. Impulse noise 3. Echoes 4. Intermodulation
What is the difference between white Gaussian noise and additive white Gaussian noise?
A Gaussian noise is a type of statistical noise in which the amplitude of the noise follows that of a Gaussian distribustion whereas additive white Gaussian noise is a linear combination of a Gaussian noise and a white noise (white noise has a flat or constant power spectral density).
Is salt and pepper noise an impulse noise?
Yes, salt and pepper noise is a type of impulse noise. It manifests as random bright (white) and dark (black) pixels in an image, resembling grains of salt and pepper. This noise occurs due to sudden disturbances in the signal, often resulting from transmission errors or sensor faults. It is characterized by its sporadic nature, differentiating it from other types of noise like Gaussian noise.
What does the shannon capacity have to do with communication?
It has to do with data communication. It is called the Shannon channel capacity theory where double the bandwidth equals double the highest data rate. This is of course theoretically and does not take into account white noise (thermal noise), impulse noise, attenuation distortion or delay distortion.

How do you tell the difference between a rat impulse paintball markers?
the Rat Impulse LTD has: a regulator, The regular Rat Impulse does not.
Which type of distortion occurs when a connection cable is inadequately insulated?
Impulse noise
What is the difference between white noise and gaussian noise?
White noise is a type of signal that has a flat power spectral density across all frequencies, meaning that all frequencies have equal power. Gaussian noise refers to noise with a normal distribution in the time domain. While white noise has uniform power across all frequencies, Gaussian noise has a distribution of values that follows the Gaussian (bell-shaped) curve.
Difference between impulse and momentum?
Impulse is another name for change in momentum.Both momentum and impulse have same unit( Ns or kgm/s) . Impulse is also defined as force acting for a time "t". so, Impulse=F*t
