A wavelet is a small localized wave based on a mathematical function. Wavelet analysis is able to represent signals in the time and frequency domains at the same time. Many modern applications have ...

Abstract: Speech signal is a non-stationary short-time transient signal. The useful signal is in the same frequency range as the noise. The traditional de-noising method in the form of filter can not ...

This MATLAB project proposes a fast and reliable protection scheme for double transmission lines using transient current signals. Discrete Wavelet Transform (DWT) is employed to extract high-frequency ...
