Abstract
RECEPTOR DE RADIO PARA RECIBIR SEN/ALES MODULADAS EN FRECUENCIA EN UNA SEN/AL PORTADORA DE ALTA FRECUENCIA.CONSISTE EN SOMETER SEN/ALES DE BANDA DE BASE (I, Q) EN CUADRATURA, CON FRECUENCIA MEDIA IGUAL A CERO, A UNA LIMITACION MEDIANTE AMPLIFICADORES (11, 12), PARA FORMAR SEN/ALES DE ONDA CUADRADA, EXISTIENDO UNAS REDES DE FORMACION DE IMPULSOS (13, 14), QUE PROPORCIONAN UNAS SECUENCIAS DE LOS MISMOS, CUYAS FRECUENCIAS REPRESENTAN LOS CAMBIOS DE POLARIDAD EN LAS SEN/ALES DE ONDA CUADRADA. CADA ONA CUADRADA, PASA A TRAVES DE UNOS MULTIPLICADORES (15, 16), DE MODO QUE LA SECUENCIA DE IMPULSOS DERIVADA DE LA OTRA ONDA PORIDCE UN TREN UNIPOLAR. LOS DOS TRENES SE COMBINAN EN UNA RED (17) PROPORCIONANDO UNA SEN/AL DE SALIDA DIGITAL.
