It affects the signal due to the activity present in the electrons in the medium, when the temperature increases the electrons activity increases which increases the noise and vice versa
An AWGN channel adds white Gaussian noise to the signal that passes through it.

To remove the noise
1. The bandwidth for transmission of PAM signalis very very large compared to its maximum frequency content. 2. The Amplitude of PAM Pulses varies accordingly to modulated signal. Therefore interference of noise is maximum for the PAM signal and this noise cannot be removed very easily. 3. Since amplitude of PAM signal varies, this also varies the peak power required by the transmitter with modulating signal.
A noise generator produces electrical signals in both audio and video format. These are used for troubleshooting purposes in signal circuits for amplifiers and televisions.
A: Noise effect an analog signal by adding or subtracting from the signal
White noise sounds like a hiss. It can be used in the sythesis of musical instruments or sound effects. It is random noise and can be used for signal analysis.
the bandwidth and the signal to noise ratio
Signal to noise ratio is a measure of signal strength to the background noise. Engineers use the signal to noise ratio to improve digital signal processing.
White noise is also called "snow" and it looks like a snow storm on the screen. It is the result of an analog receiver not getting a signal and it can be compared to the hiss from a radio when it loses its signal. Modern televisions often suppresses the noise and digital televisions do not suffer from it at all.
Noise signal is any signal which interferes with the main signal and does not give any important information.Signal should always be twice to that of noise.
White noise is random sound that contains an equal amount of all the frequency components across the spectrum one is testing. It sounds sorta like the hiss one hears when a television is tuned to a blank channel (if the television doesn't automatically mute the sound when no signal is present, however). If one has white noise and examines the signal level of, say, the 55 cycle per second signal component, it will be the same as, say, the 927 cycle per second signal component, or the 2651 cycle per second signal component.
