Abstract

UN METODO PARA REDUCIR RUIDO INTERCANAL O LISTON ESPECTRAL EN LA MAS RAPIDA TRANSFORMACION DE FOURIER (24) PROCESANDO DATOS DIGITALES. LOS DATOS SON OFRECIDOS Y PROCESADOS A LO LARGO DE DOS TRAYECTORIAS (16/18, 14). DURANTE EL PROCESO A LO LARGO DE LA PRIMERA TRAYECTORIA UN AFILADO FILO DISCONTINUO ES DETECTADO. PESOS SON APLICADOS A LAS MUESTRAS DE DATOS ALREDEDOR DEL FILO A CUAVIZAR LA DISCONTINUIDAD. CUANDO EL FILO ES PROCESADO POR METODOS DE TRANSFORMACION DE FOURIER, EL FILO AFILADO NO CAUSA MAS RUIDO EN EL INTERCANAL DE BANDA ANCHA.
