Abstract

UN APARATO DE DESVIACION COMPRENDE UN AMPLIFICADOR DE DESVIACION (Q2) ACOPLADO A UN CIRCUITO DE MODULACION (400) DE FORMA DE ONDA DE DESVIACION, TAL COMO UN MODULADOR DE DIODO. UNA FUENTE (U1) PARA GENERAR UNA SEÑAL DE MODULACION (E-W). LA SEÑAL DE MODULACION (E-W) COMPRENDE UN COMPONENTE DE AC (CORRIENTE ALTERNA) Y UN COMPONENTE DE DC (CORRIENTE CONTINUA), TENIENDO CADA UNO NIVELES QUE DEFINEN UNA RELACION DE AMPLITUD. UN AMPLIFICADOR (200) ALTERA LA RELACION DE AMPLITUD, Y LA RELACION DE AMPLITUD ALTERADA SE ACOPLA AL CIRCUITO (400) DE MODULACION DE FORMA DE ONDA DE DESVIACION, PARA LA MODULACION DE LA FORMA DE ONDA DE DESVIACION.
