Abstract

The invention relates to a method and an arrangement for reducing interference created in an output signal in connection with signal conversion. The arrangement may employ two structural sets, whereof the arrangement comprises at least one. The first structural set comprises a modulator (10) arranged to modulate the signal, and a DA converter (30) arranged to convert the serial-mode input signal arriving from the modulator into an analogue output signal. In addition, the first structural set comprises a serial/parallel converter (20) arranged to convert the modulated signal into parallel mode, and a divider (40) for generating a clock signal, the frequency of the clock signal generated by the divider being lower than the frequency of the clock signal used in serial-mode input signal transmission. The divider (40) is arranged to simultaneously clock several signals to the DA converter (30). The second structural set comprises an AD converter (70) arranged to convert an analogue input signal into several parallel digital output signals. In addition, the second structural set comprises a parallel/serial converter (80) arranged to receive several simultaneously arriving digital signals for conversion into serial-mode signals using a clock signal, the frequency of which being lower than the frequency of the clock signal used in serial-mode signal transmission.
