Modelos de respuesta en frecuencia
Un modelo de respuesta en frecuencia es la respuesta en frecuencia de un sistema lineal evaluado en un intervalo de valores de frecuencia. El modelo está representado por un objeto de modelo idfrd que almacena la respuesta en frecuencia, el tiempo de muestreo y la información del canal entrada-salida.
