Abstract: Degradation of signals by noise is a very common problem in today’s world .As we know that noise is the main factor that affect the accuracy of results in the signals. It is due to the rapid growth of latest technologies .Noise is added by various factors like heavy machines, loud music, heavy vehicles and noisy engines .Noise is basically unwanted signals which cause disruption of original signals. There are various ways by which we can restore original signals from the distorted signals. Lots of research is conducted for the improvement of results .The best motivational factor to be consider is wavelet. Wavelet denoising attempts to remove the noise present in the signal while preserving the signal characteristics, regardless of its frequency content. . In this paper, the author compares the performances of Haar, Coiflet and BIORSPLINE Wavelets for different values of their order for a sine signal. The variation of correlation value with the wavelets order has been investigated.
