Abstract
Se describen un metodo, aparato y programa de computadora para mejorar la relacion senal-ruido de una senal S(t), S(t) contiene Senal y ruido. Se obtiene una medicion de S(t) en una frecuencia de interes. Se obtienen mediciones de ruido de S(t) en una o mas frecuencias de ruido donde se espera que la porcion de Senal de S(t) sea pequena. El ruido en la frecuencia de interes se estima utilizando las mediciones de ruido en una o mas frecuencias de ruido. El ruido estimado se sustrae de las mediciones de S(t) en la frecuencia de interes.
