Abstract
EL INVENTO SE RELACIONA CON LA TECNICA DE PUESTA EN FUNCIONAMIENTO Y CONTROL DE FILTROS ACTIVOS CONTROLABLES ELECTRICAMENTE. DE ACUERDO CON EL MISMOS LOS FILTROS SE CONTROLAN Y PONEN EN UTILIZACION CON UN SISTEMA DE GANANCIA DIFERENCIAL QUE INCLUYE UN PAR DE COMPONENTES AMPLIFICADORES (Q111 Y Q121, Q112 Y Q122, Q113 Y Q123) Y GRUPOS DE DIODOS CONECTADOS EN SERIE ASI COMO AL MENOS UN GENERADOR DE CORRIENTE (Q1, Q2, Q3). LA CAIDA DE TENSION DIRECTA DE LOS DIODOS TIENE LA MISMA RESPUESTA DE CORRIENTE QUE EL VOLTAJE EMISOR DE BASE DE LOS AMPLIFICADORES. UN FILTRO DE PRIMER ORDEN INCLUYE UNA FASE DE GANANCIA DIFERENCIAL CON UN CAPACITOR (C) CONECTADO A LA SALIDA DE DICHA FASE O A SUS COMPONENTES DE AMPLIFICACION. UN FILTRO DE SEGUNDO ORDEN PUEDE INCLUIR DOS FASES DE GANANCIA DIFERENCIAL, CADA UNA CON SU COMPONENTE CAPACITIVO (C1,C2) EN EL CIRCUITO. UN OSCILADOR PARA CONTROLAR LOS FILTROS CONSTA DE TRES FILTROS DE PASO BAJO CONECTADOS EN SERIE, CADA UNO DE LOS CUALES INCLUYE SU FASE DE GANANCIA DIFERENCIAL.
