This paper address the PCG signals (Phonocardiogram) and their De-noising techniques. The PCG as a kind of weak biological signal under the back ground of strong noise is easily subject to interference from noise of various sources. De-noising of PCG signal therefore, forms the primary basis for achieving non-invasive diagnosis of coronary heart disease. There are various method are available for De-noising the PCG signal but the method is most effective for the PCG signal is very much important. In this paper de- noise the 4 types of PCG signal and check the different parameters and find that which wavelet gives the maximum result for all four types PCG signals.


PCG signals, Wavelet Transforms.
