The anti-jamming measures of reading and writing signals in the parallel transmission

摘要

Study the relations between reading and writing control signals and transmission medium in the long distance parallel transmission and their waveforms, and find out the reliable transmission technological approach of reading and writing control signals. Adopt the re-triggering monostability trigger to process reshaping and anti-jamming on the rising edge or the falling edge of waveforms to eliminate the reflection jam on the edge. As indicated by practice, the anti-jamming effect of this method is in evidence, with the result of the error code ratio dropping to 10~(-7) hereinafter. This method solves multi-dither problems, which arise on the rising edge and the falling edge of reading and writing control signals and are caused by asymmetrical impedance distribution of the transmission medium in parallel transmission, and is of high value on the application.
