Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO TRABAJANDO DIGITALMENTE, PARTICULARMENTE PARA LA DETECCION DE LA FRECUENCIA MOMENTANEA, PARTICULARMENTE PARA ELEVADA FRECUENCIA ( > 100 MH2) Y DURACION DE A MEDICION CORTA (< 100 NS), QUE PARTICULARMENTE SE PRESENTAN EN PROCEDIMIENTO FSK Y/O PSK PERO TAMBIEN GENERALMENTE EN PROCEDIMIENTO DE COMUNICACION Y/O RADAR. POR ELLO SE CUANTIZA EN FASE PRIMERAMENTE SEÑALES DE ENTRADA ANALOGAS Y A CONTINUACION CON AYUDA DE UNA FORMACION DE VALOR MEDIO SE TRANSFORMA EN TERMINOS DE FRECUENCIA DIGITAL CORRESPONDIENTE. POR ELLO SE LOGRA UNA SOLUCION DE FRECUENCIA ELEVADA CON UN DISPENDO DE CONEXION ECONOMICO Y PEQUEÑO.
