Abstract
LA INVENCION SE REFIERE A UN CIRCUITO PARA LA AMPLIFICACION DE SEÑALES DE UN MICROFONO, QUE COMPRENDE UNA FUENTE DE ALIMENTACION Y UN GENERADOR DE CORRIENTE QUE ALIMENTA UN MICROFONO, POR EJEMPLO UN MICROFONO ELECTRET CON ENERGIA ELECTRICA EN FORMA DE IMPULSOS. EL CIRCUITO CONECTA DE FORMA TEMPORIZADA LA FUENTE DE ALIMENTACION AL MICROFONO CON UN TIEMPO DE IMPULSO ACTIVO T1, Y EL CIRCUITO DE MUESTREO LEE LA SEÑAL DEL MICROFONO EN UNA VENTANA, CALCULANDOSE LA DURACION T2 A PARTIR DEL FLANCO POSTERIOR DE LA PARTE ACTIVA DEL CIRCUITO DE ALIMENTACION, CON LO CUAL T1 ES MAS BREVE QUE EL PERIODO DE TIEMPO T QUE CORRESPONDE A LA FRECUENCIA DE MUESTREO 1/T, Y T1 TIENE UNA LONGITUD QUE ES SUFICIENTE PARA PERMITIR QUE LA CORRIENTE MICROFONICA ALCANCE UN VALOR UTILIZABLE, PUDIENDO T2 SER MAS CORTA QUE T1.
