An Overview of Noise Cancellation Techniques

Noise are the unwanted signal or disturbance in the network, there are many sources form where we can get the disturbance in the signal due to with the fidelity of the signal gets low and hence we are not able to understand the message or actual inputs from the speaker. In the paper we try to elaborate the techniques to mitigate the nose signal or noise channel so as to capture the original signal with high fidelity. On the contrary the noise channel may cause several health issues such as loosing the hearing ability hence we need such system which ensures the protection to human system damages from noise.
