| Adding Noise to a signal |
Noise can be described as "any unwanted signal that present in a communication system"
Noise is a mixture of sinusoidal signals with different frequencies and aptitudes.
Information Transmission is affected by noise if any frequency component of the noise signal is fallen in to the pass band (frequency spectrum) of the information signal.
