Abstract

SE REVELA UN APARATO PARA LA REGULACION DE AMPLITUD DIGITAL, PARA UTILIZARSE COMO CONTROL DE VOLUMEN O SIMILAR, QUE EMPLEA LA MODULACION DE LA AMPLITUD DE PULSACION PARA CONTROLAR UNA TRANSMISION DE SEÑAL A TRAVES DE UN ELEMENTO NO-LINEAL DE DOS TERMINALES, CUYA RESISTENCIA VARIA CON LA CORRIENTE, P. EJ., UN DIODO (74) O UN ELEMENTO SIMILAR AL DIODO. UNA CORRIENTE DE IMPULSOS (54), CUYO REGIMEN DE TRABAJO ES VARIABLE Y ESTA CONTROLADO DIGITALMENTE, SE FILTRA (56, 58) PARA PRODUCIR UNA SEÑAL DE REFERENCIA VARIABLE CASI CONTINUA (50). EL VALOR DE LA SEÑAL DE REFERENCIA REGULA EL AUMENTO CONTROLANDO EL COMPONENTE DE LA SEÑAL (65) DE INTERES QUE ESTA YA DISPONIBLE PARA SU AMPLIFICACION. PARA LA REALIZACION A BAJO COSTE EN UN SISTEMA QUE YA EMPLEE UN MICROPROCESADOR O MICROORDENADOR EL REGIMEN DE TRABAJO DETERMINATIVO PUEDE DERIVARSE BAJO CONTROL DE SOFTWARE Y SUMINISTRARSE COMO UNA SALIDA DE UNA UNICA ESPIGA DE SALIDA RETENIBLE (54). EN UNA REALIZACION EJEMPLAR, UN COMPONENTE DE DC DERIVADO DELOS IMPULSOS DEL REGIMEN DE TRABAJO VARIABLE CONTROLA EL VOLTAJE DE SALIDA DE DC DESDE UN DIVISOR DE CORRIENTE (62, 64) Y SE UTILIZA PARA REGULAR LA MAGNITUD DE UNA SERIE DE IMPULSOS DE MAGNITUD FIJA (65). ADICIONALMENTE, EL USO DE UN FILTRO DE UN TIPO ALMACENADOR DE ENERGIA (56, 58) PERMITE QUE LA CORRIENTE CONTINUA DE IMPULSOS DE UN REGIMEN DE TRABAJO VARIABLE SE INTERRUMPE MOMENTANEAMENTE DE TAL FORMA QUE UNA ESPIGA UTILIZADA PARA SUMINISTRAR LOS IMPULSOS PUEDA EMPLEARSE EN LA REALIZACION DE FUNCIONES ADICIONALES SIN AFECTAR EL NIVEL DE VOLUMEN PERCIBIDO.
