Abstract:
1. A method for decoding a signal transmitted via at least one connecting line of a data transmission system in a user of the data transmission system receiving the signal, the data transmission system including a plurality of users having connecting lines between the users, comprising: transmitting data coded in the signal in data frames having a defined structure, the data being transmitted serially bit-by-bit; sampling each bit in the receiving user using a plurality of clock pulses; and predefining, within a data frame, synchronization points for reference of an instant of a sampling for each received bit; and measuring an interval of a change, provided compulsorily in a transmission protocol used in the data transmission system, of the signal one of (a) from rising to falling and (b) from falling to rising edge; calculating a value of the asymmetrical delay of the transmitted signal as a difference between an actual length of the measured interval and a specified length for the measured interval; and executing suitable measures for improving the sampling of the received bits as a function of the calculated value of the asymmetrical delay of the transmitted signal.
