Abstract
UN CODIFICADOR Y DECODIFICADOR DE BIT - SIMPLE ADAPTADO TIENE SU FUNCION ADAPTADORA DETERMINADA POR DIVIDIR DINAMICAMENTE LA BANDA DE FRECUENCIA DE MENSAJE DENTRO DE REGIMENES DE MODULACION DELTA - SEGURA Y DELTA DE OPERACION. EN UNA PRACTICA ESTA ES ACOPLADO POR VARIAR LA FRECUENCIA DE PICO DE UN FILTRO (14, 14'') PASO - BAJO DE FRECUENCIA VARIABLE EN UN INTEGRADOR NO HERMETICO TAL QUE ABAJO DE LA FRECUENCIA DE PICO LA OPERACION ES LA DE MODULACION DELTA SEGURA Y ARRIBA LA FRECUENCIA DE PICO DE LA OPERACION ES LA DE MODULACION DELTA. UN CIRCUITO (18, 18'') DE CONTROL DE ADAPTACION MUEVE EL COMPONENETE DE LA SEÑAL DE RELOJ DESDE EL CHORRO DE BIT CODIFICADOS PARA PROVEER UNA SEÑAL ANALOGA REPRESENTATICA DE LA INFORMACION DEL CHORRO DE BIR O CARGA PARA USO EN GENERAR LA SEÑAL DE CONTROL. LA SEÑAL ANALOFOA ES MAXIMA RECTIFICADA (22, 22''), IGUALADA (24, 24'') Y (OPCIONALMENTE) PROCESADA (26, 26'') NO LINEALMENTE PARA PROVEER LA SEÑAL DE CONTROL.
