The invention relates to a method for preparing a synthetic talc composition. The first baseband processor functions as system master, and the second processor functions as system slave. Program listings are supplied to the program guide. The soft magnetic material has an electrical resistivity of not less than 3,000 \u03bc\u03a9cm and not more than 50,000 \u03bc\u03a9cm, and a magnetic permeability \u03bc of not less than 2,000 and not more than 4,000.
