Abstract

Este artículo presenta una corta explicación de la teoría básica del análisis Wavelet y una de sus aplicaciones en la reconstrucción de señales. Inicialmente se hace una comparación con el análisis de Fourier y se justifica la importancia y necesidad de utilizar la Transformada Wavelet. Luego se presenta matemáticamente la transformada Wavelet Continua, se discretizan los parámetros de tiempo y frecuencia obteniendo la Transformada Wavelet Discreta, por último se explica la forma en que se puede descomponer y representar una señal sinusoidal por medio de los coeficientes de escala ycoeficientes Wavelet utilizando como función base la Wavelet Madre Haar.
