Abstract
CIRCUITO CORRECTOR DE LINEALIDAD PARA TRANSMISIONES DE TELEVISION QUE FUNCIONA CON UNA FRENCUENCIA INTERMEDIA Y QUE INTRODUCE UNA DISTORSION PREVIA ADECUADA EN LA AMPLITUD DE LA ENVOLVENTE PARA COMPENSAR LA NO LINEALIDAD DE LOS ESTADOS DEL AMPLIFICADOR. UNA SERIE DE FUENTES DE INTENSIDAD PARALELAS (11), CADA UNA DE LAS CUALES ES AJUSTABLE INDEPENDIENTEMENTE DE LA RESPUESTA A LA DISTORSION PREVIA DE LA AMPLITUD DE BANDA CORRESPONDIENTE, PRODUCE UNA CORRIENTE SUFICIENTE PARA PROPORCIONAR UNA DIFERENCIA DE POTENCIAL ADECUADA EN LA SALIDA. EL CIRCUITO ES CAPAZ DE CORREGIR INDEPENDIENTEMENTE CADA ANCHO DE BANDA, DE FORMA QUE ES CAPAZ DE FUNCIONAR BAJO EL CONTROL DE UN MICROPROCESADOR EN TIEMPO REAL.
