Abstract
MÉTODO E SISTEMA PARA DETERMINAR COMPONENTES DE VETOR DE FASE DE UMA FORMA DE ONDA PERIÓDICA. A presente invenção refere-se a um método de determinar componentes de vetor de fase de uma forma de onda periódica, em que o método compreende: a) amostrar a forma de onda periódica, b) determinar um espectro de frequência da forma de onda periódica amostrada por meio de uma transformação de frequência utilizando uma função de janela Gaussiana, em que uma relação np definida pela duração (T0) da amostragem da forma de onda periódica dividida pelo parâmetro de largura (tw) da função de janela Gaussiana é pelo menos 5, c) selecionar uma região do espectro de frequência contendo um pico de frequência definido por um grupo de caixas de frequência consecutivas cada uma sendo definida por um valor de frequência e um valor de magnitude, e d) determinar os componentes de vetor de fase da forma de onda periódica baseado no grupo de caixas de frequência consecutivas.
