Abstract

SE EXPONE UN APARATO Y METODO CUYA FASE BLOQUEA UNA SEÑAL DE SALIDA MODULADA DE FRECUENCIA AGIL A CUALQUIER CANAL SELECCIONADO DE UNA SALIDA GENERADA DE BARRIDO (25). SE BUSCA EL ERROR DE LA FASE DE UNA SEÑAL DE ENTRADA (14), SE MODULA LA SEÑAL DE ENTRADA HASTA UNA FRECUENCIA DE SALIDA DE PORTADORA Y, LA FRECUENCIA DE SALIDA MODULADA SE CIERRA A LA SALIDA DEL GENERADOR DE BARRIDO AL SUSTRAER LA SEÑAL DE ENTRADA Y NEGAR EL ERROR DE LA FASE.
