MAGNETIC FILTER

摘要

PROBLEM TO BE SOLVED: To filter a plurality of frequency signals by using magnetic tunnel junction. SOLUTION: The present invention includes a magnetic filter (700). The filter (700) includes a magnetic converter (710) for generating a magnetic field (720) in response to a plurality of information carrier signals. The magnetic filter (700) further includes the magnetic tunnel junction (730). The magnetic tunnel junction (730) can be tuned so as to switch a state in response to the selected frequency of the magnetic field (720). The magnetic filter (700) can further include a magnetic tunnel junction sensor (740) for detecting the state of the magnetic tunnel junction (730). COPYRIGHT: (C)2005,JPO&NCIPI
