Resumen:

In this work the fractal dimension was calculated (FD) using the Higuchi's algorithm in time domain, with the objective of identified the echoes contained in ultrasonic signals, in order to differentiate echoes from oscillations due to electric noise. Once the echo reference (signal) was set, the wavelets scales were chosen (Morlet, Mexican Hat y Daubechies 5); from all these, the Wavelet Morlet has the best performance, therefore this was used to estimate time delays in the ultrasonic signals acquired in water.
