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.
A downward change in signal strength where the wave 'Fades' from distance lmitations, interference, noise or EMI.
RAD Data Communications's population is 1,100.
RAD Data Communications was created in 1981.
Noise
Noise
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.

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).
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
