AB  - Several factors are responsible for signal corruption but the most common factors are attenuation distortions, delay distortion and noise. Noise is a major limiting factor in communication system performance and they are caused by several means over various channel. In this research, a model was developed by the use of an application in MATLAB called simulink to simulate the effect of distortion on signals and adaptive filtered was also modeled to filter the noise that constitute the distortion. It was found out that by the use of an adaptive filter noise cancellation could be effected. The results are graphically displayed by the various graphs of the input signal, signal with noise and the filtered output.
