Transformada corta de Fourier

Abstract

En este documento se muestran aspectos generales acerca de la transformada de Fourier, definida como un operador entre espacios de Hilbert y finalmente se presenta el concepto de transformada corta de Fourier como respuesta a las funciones de frecuencia variable con el tiempo, como lo es la función Chirp. This document shows general aspects about Fourier`s Transform ,as operator between Hilbert spaces,finally,it shows the concept of Fourier´s Short Transform as an answer to the functions of variable frequency with time, like chirp function is.
