Abstract
PROCEDIMIENTO Y APARATO PARA DETECTAR LA PRESENCIA DE UNA SEN/AL QUE EXHIBE UNA FRECUENCIA PREDETERMINADA.CONSISTE EN: A) GENERAR UNA SEN/AL DE INTERVALO DE OBSERVACION; B) MUESTREAR LA SEN/AL PARTICULAR DURANTE LA VENTANA DE OBSERVACION PARA PRODUCIR MUESTRAS DE LA SEN/AL PARTICULAR; C) IGNORAR UNA PORCION DE LAS MUESTRAS DE LA SEN/AL PARTICULAR QUE SE PRESENTA EN UN TIEMPO PROXIMO AL COMIENZO O AL FINAL DE LA VENTANA DE OBSERVACION; Y D) CORRELACIONAR LAS MUESTRAS DE LA SEN/AL PARTICULAR QUE NO SON IGNORADAS CON UN MODELO PREDETERMINADO PARA DETECTAR LA PRESENCIA DE UNA SEN/AL QUE EXHIBE DICHA FRECUENCIA PREDETERMINADA. CONSTA DE UN CIRCUITO TEMPORIZADOR (40); UN CIRCUITO DE MUESTREO (30); UN CIRCUITO DE IGNORANCIA Y UN CIRCUITO DE CORRELACION (60) ELECTRICAMENTE CONECTADO AL CIRCUITO DE MUESTREO.
