Beschreibung
Zusammenfassung:	A low-pass filter 10 on a microprocessor bus 22 for attenuating radio frequencies from digital signals travelling on the bus 22 from a microprocessor 12 to a peripheral device 20 . An RC network is implemented as close as physically possible to the junction of the bus connection to microprocessor 12 and memory 14 to filter radio frequencies to an extent that limits radiation of these frequencies from the length of the bus 22 . Wait states are adjusted as necessary to accommodate filtering of the digital signal that is transmitted over microprocessor bus 22.
