Abstract:
The wavelet theory is a powerful method for processing different signals. In this report a new wavelet was obtained. This approximated delta wavelet is based on an approximation of a delta window. From the admissibility condition in the case of wavelet regular enough we have: i) the wavelet Fourier transform in origin equal to zero and ii) the wavelet has zero mean. This transform is a more flexible one because is dependent on three parameters and can cover more combinations of discrete and continuous parameter discretisations (hybrid cases).
