A method for transmitting bitstreams in a daisy chain communication bus system comprising a bus master and a plurality of slaves connected in series into a data bus connected to the bus master, wherein a bitstream is received as a reception bitstream by a slave and is transmitted by the same to an adjacent slave as a transmission bitstream, wherein, according to the method, in a slave - a reception bitstream is scanned using a scanning signal whose frequency is formed from the clock frequency of an internal clock oscillator signal by a frequency divider to which the clock oscillator signal is supplied, - wherein the frequency of the internal clock oscillator signal is higher by less than one decimal power than the frequency at which the bits of the reception bitstream succeed each other, - wherein the frequency divider is a rational frequency divider which generates a scanning signal from the internal clock oscillator signal, which scanning signal has a rational frequency ratio of 2 -m, either integral or broken in powers of two, to the clock oscillator signal, wherein m is a natural number greater than 0, - wherein the scanning signal is synchronous with the reception bitstream with regard to frequency and/or phase and - wherein the frequency divider is supplied with the output signal of an edge detector detecting signal edges of the input bitstream, - the individual bits of the reception bitstream being scanned by means of the scanning signal, - the end of the transmission period of ach bit of the reception bitstream being detected and this information being supplied to the frequency divider, - a transmission bitstream being formed in a bit-wise manner as the reception bit stream is received, by completing, after the end of the transmission period of a bit of the reception bitstream, the transmission bitstream with a bit which is logically identical to the respective received bit and subsequently transmitting the same, and - the chronological sequence of the bits of the transmission bitstream is equal to the chronological sequence of the bits of the reception bitstream and occurs based on the frequency of the scanning signal. - a reception bitstream is scanned using a scanning signal whose frequency is formed from the clock frequency of an internal clock oscillator signal by a frequency divider to which the clock oscillator signal is supplied, - wherein the frequency of the internal clock oscillator signal is higher by less than one decimal power than the frequency at which the bits of the reception bitstream succeed each other, - wherein the frequency divider is a rational frequency divider which generates a scanning signal from the internal clock oscillator signal, which scanning signal has a rational frequency ratio of 2 -m, either integral or broken in powers of two, to the clock oscillator signal, wherein m is a natural number greater than 0, - wherein the scanning signal is synchronous with the reception bitstream with regard to frequency and/or phase and - wherein the frequency divider is supplied with the output signal of an edge detector detecting signal edges of the input bitstream, - the individual bits of the reception bitstream being scanned by means of the scanning signal, - the end of the transmission period of ach bit of the reception bitstream being detected and this information being supplied to the frequency divider, - a transmission bitstream being formed in a bit-wise manner as the reception bit stream is received, by completing, after the end of the transmission period of a bit of the reception bitstream, the transmission bitstream with a bit which is logically identical to the respective received bit and subsequently transmitting the same, and - the chronological sequence of the bits of the transmission bitstream is equal to the chronological sequence of the bits of the reception bitstream and occurs based on the frequency of the scanning signal.
