PURPOSE:To remove disturbing waves effectively by providing filter elements for each disturbing wave to be removed and then by arraying filter elements for removing one disturbing wave among those for the other in sequence. CONSTITUTION:On substrate 1 with stuck earth conductor 2, filter elements 51, 52... are arranged. Those filter elements stand on substrate 1 while each bobbin 6 is soldered to earth conductor 2 at its flank, and capacitor 10 is connected to each element wound with primary coil 8 and secondary coil 9. Then those filter elements adjoin to one another so that disturbing waves of different channels will be removed. |
