Abstract

PROCESO PARA DETERMINAR LA TRANSMITENCIA DE UN CIRCUITO DE FILTRADO (3) PREVISTO PARA TRANSFORMAR LA RESPUESTA IMPULSIONAL M(Z) DE UN FILTRO (2) EN UNA RESPUESTA DE FASE MINIMAL. EL PROCESO COMPRENDE UN CALCULO DE LA RESPUESTA TEORICA EN FRECUENCIA DEL CIRCUITO DE FILTRADO (3) Y DE LA RESPUESTA IMPULSIONAL EN FRECUENCIA EN FASE MINIMAL, IMPONIENDO UNA CONDICION DE CAUSALIDAD SOBRE LA RESPUESTA DE FASE MINIMAL, UNA DETERMINACION DE LA TRANSMITENCIA TEORICA EN FRECUENCIA, UNA ESTIMACION DE LA TRANSMITENCIA DEL CIRCUITO DE FILTRADO (3) POR TRUNCADURA DE LA TRANSMITENCIA TEORICA EN LA CUAL NO SON CONSERVADOS MAS QUE UN NUMERO PREDETERMINADO DE COEFICIENTES, Y UNA DETERMINACION DE LA RESPUESTA GLOBAL EN FASE MINIMAL A PARTIR DE UN DESARROLLO LIMITADO DE LA CEPSTRE.
