MULTICHANNEL TRANSMISSION ON UNIFILAR BUS

摘要

The invention relates to a method for transmitting an at least synchronization and data signal (S) on a unifilar bus between a master device and at least one slave device, wherein a first transmission channel (C1) from the master device to the slave device modulates the periodic pulse width between a first level (V0) and second level (V1) of a same sign voltage relative to a reference potential, and a second transmission channel (C2) amplitude modulates at least one of the voltage levels between said level and at least one third level (V0') different from the two others and from the reference potential.
