Apresentar os algoritmos e modelos mais importantes de filtragem adaptativa, de processamento de sinais de voz e de redes neurais e suas aplicações em controle, telecomunicações, estimação e predição. To learn digital filter design technique and acquire working knowledge in order to apply them to filter synthesis from specifications as used in practical applications. The application of previously learned signal and transform concepts is required and the students are expected to crystallize them by this process. On the other hand, this subject provides the basic concepts for the realization of filters and adaptive models which will be dealt with by more advanced subjects.
