ABSTRACT:
A filtering circuit and technique that is especially adapted to remedy the possibility of pulses from becoming corrupted when passing between a microcomputer unit and one or more peripheral devices, as they are communicated over an interconnecting cable, to the point of causing errors to occur in operation of the computer system. The specific circuit disclosed is especially adapted to operate with a small computer system interface ("SCSI") interconnecting bus standard. Adverse effects of false pulses created by voltage supply variations on the interconnecting cable and reflections of pulses along the cable due to impedance mismatches are remedied.
