Abstract
A passive cascaded low-pass and high-pass filter comprises a conductive ferrite block (100) for filtering out some and not others of the frequencies of a multi-frequency electrical signal, and a pair of electrical contacts (101) on the block for connecting the unfiltered signal to the block and connecting the filtered signal from the block. The filter characteristic depends upon the ferrite's stoichiometry, but is independent of the ferrite's geometry. Signal attenuation caused by the filter evenly across the whole frequency range can be varied by varying the stress between one or both contacts and the block, via various stress-inducing mechanisms (400, 500).
