Abstract

UN MEZCLADOR CON RECHAZO DE IMAGEN CONTIENE LOS MEDIOS PARA AÑADIR UNA SEÑAL A LA SEÑAL DE ENTRADA DE RF. CUALQUIER DESEQUILIBRIO EN EL CIRCUITO DE MEZCLA, QUE CONDUCIRIA A UNA SUPRESION IMPERFECTA DE IMAGEN, ES CORREGIDO MEDIANTE LA DETECCION DE CUALQUIER COMPONENTE DE OSCILACION LOCAL RESULTANTE EN LA SEÑAL DE SALIDA DEL MEZCLADOR, Y EL AJUSTE DEL BALANCE PARA MINIMIZAR EL TAMAÑO DE ESA COMPONENTE.
