LOGICAL SIGNAL TRANSMISSION METHOD

摘要

The invention relates to a method of repeated serial transmission on a single channel (cable, radio connection) of available logical signals with a low variation rate, parallel to the transmission section of the system and, if necessary, parallel to the receiving section, e.g., for the condition of relays that needs to be remotely transmitted. This is a unique channel transmission without a separate synchronization channel. Synchronization is achieved on the last channel when there are no pulses on the transmission line. The increase in sensitivity to interference is achieved through the control of the multiplexer/demultiplexer by the higher output of a counter with several positions, which is based on the period of the oscillator being much lower than the period assigned for one channel transmission. In addition, stability to interference is increased by using a filtering circuit for the demultiplexer output that prevents changes in the value of logical signals output as a result of interference or instability of input logical signals.
