Abstract

Metodo para el reconocimiento de senales, siempre que la senal esta limitada en el tiempo y sea periodica, que comprende la obtencion de la envolvente, la toma de muestras del valor instantaneo de su amplitud que mediante diversos parametros temporales y su comparacion con diferentes matrices de referencia, que permiten identificar su pertenencia a una de dichas matrices mediante el uso de un microcontrolador de bajo costo, ya que la potencia de calculo necesaria es para realizar operaciones basicas de calculo, incorporadas en los microcontroladores mas sencillos.
