Abstract
A method is described for the transmission of data among devices (D, D, . . . D, . . . D) connected to a communication channel (1) through sequences containing at least two symbols, one dominant ('0') and one recessive ('1'). According to this transmission method, one (D) of the devices connected to the communication channel (1) has the function of time slot generator and it transmits on the communication channel (1) with a transmission frequency (f) a sequence of symbols, each defining a time slot in a sequence of time slots. The sequence of symbols comprises at least a series of recessive symbols (“1”). When one of the devices (D) has to transmit on the communication channel (1), it generates a sequence of symbols, synchronized with the sequence of time slots generated by the time slot generator device (D) and comprising at least one dominant symbol (“0”).
