What does shannon capacity have to do with communications?
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.
What is signal degradation in data communications?
A downward change in signal strength where the wave 'Fades' from distance lmitations, interference, noise or EMI.
What is RAD Data Communications's population?
RAD Data Communications's population is 1,100.
When was RAD Data Communications created?
RAD Data Communications was created in 1981.
Electrical disturbance that can degrade communications?
Noise
What is electrical disturbance that can degrade communications?
Noise
What is the difference between analog and digital communications?
Analog means continuous transmission of data whereas digital means discrete transmission of data. In analog communications we are transmitting finite amount of data in infinite amount of information. so,there is a possibility of occurrence of noise. where as in digital we are transmitting finite amount of data in finite amount of information. so , out of these two, digital is most efficient.

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).
What does a basic communications system consists of?
A basic communications system consists of---------- 1.Two computers, one to send and one to receive data 2.communications devices that send and receive data 3. a communications channel over wich data is sent 4.All of the above
The transmission of data from one location to another is known as data?
communications
What do you mean by Gaussian noise?
Gaussian noise is similar to white noise, but it falls within a narrower range of frequencies. In communications, it is produced by the movement of electricity through the line. You see and hear that when you have your television on an empty channel. Within photos and videos, Gaussian noise is in the form of random patterns, and this is what makes things look slightly blurry.
