Abstract

Filtro eléctronico de recepción para modem de 1200 baudios, esencialmente caracterizado por constituirse mediante un circuito electrónico que comprende siete etapas activas a base de amplificadores operacionales, de los cuales la etapa de entrada es célula ecualizadora conectada a urna célula con cero que antecede a la tercera etapa o célula paso bajo a la que sigue una célula con cero y una paso alto con cero, consistiendo la etapa final y una célula paso banda que devuelve la señal filtrada a oportunos circuitos del modem.
