Abstract

"FILTRO PARA SEGMENTAR LINHAS DE FORçA EM COMUNICAçõES". é fornecido um método para bloquear uma parte da energia de um sinal em uma linha de força. O método inclui equipar um núcleo magnético de alta freq³ência com uma bobina, conectar um capacitor através de terminais da bobina, para criar um circuito ressonante que ressoe a uma freq³ência do sinal, e colocar o núcleo magnético em volta da linha de força, em um local onde o bloqueio é desejado.
