Abstract: A printed circuit (PC) board-mountable ferrite electromagnetic interference (EMI) filter (702, 1003, 1003") for striplines (701, 1001, 1002) of a printed circuit (PC) board (700, 1000) that accommodates large numbers of striplines, and is cost-effective. One embodiment of the EMI filter is used with a PC board (700) that routes striplines (701) in a step-function (i.e., a "U"-shaped) pattern. The EMI filter comprises a ferrite body (702) that defines two parallel passageways (708, 709), i.e., has a figure-8 shape in cross section. The portion (710) of the PC board that defines the stripline portions extending in the one direction lies in one passageway, whereas the portion (711) of the PC board that defines the stripline portions extending in the other direction lies in the other passageway. A different embodiment of the EMI filter is used with a PC board (1000) that routes sets (1001, 1002) of striplines in a cross-hatch (i.e., a "#"-shaped) pattern, where the striplines end (are interrupted) before intersecting so that each stripline comprises two separate straight on-board parts. This EMI filter comprises a ferrite body (1003) that defines two orthogonal sets (1012, 1013) of off-board "U"-shaped conductors, one set for each orthogonal set of striplines with one conductor of a set for each stripline of a set. Each stripline's corresponding "U"-shaped conductor interconnects the two straight on-board parts of the stripline.

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).

Abstract: A passive positive-gain equalizer comprises a ferrite (100, 300) electromagnetically coupled to a single conductor (111, 311) of a digital signal defined in the frequency domain by a plurality of frequencies. Although it has no external power source other than the digital signal, the equalizer amplifies some of the signal's frequencies. In one embodiment, the equalizer (100) comprises a "C"-shaped body portion (101) whose legs (103, 104) extend through holes in a PC board (110) to be spanned by an "I"-shaped body portion (102). A tunnel (106) formed thereby surrounds a stripline (111) and the PC board portion (112) which carries the stripline. In another embodiment, the equalizer (300) comprises an "E"-shaped body portion (301) whose legs (303-305) extend through holes in a PC board (310) to be spanned by an "I"-shaped body portion (302). A pair of tunnels (306, 307) is formed thereby, and the stripline (311, 511) loops through each of the tunnels one or more times. The equalizer is tunable over a range of frequencies by varying the length or the number of the tunnels, by varying the number of loops the stripline makes through the tunnels, or by varying the number of the equalizers (300, 311) that are cascaded in series on the stripline (1211). Performance is improved by coupling a ferrite choke (800) in series with the stripline (111, 311) at the final output of the digital signal from the equalizer.
