ABSTRACT:
A non-contacting data path for rotating data transmission of digital data from a data source to a data sink includes at least one clock modulator. A data clock frequency is specifically modulated with the clock modulator to widen a spectrum of data signals and achieve improved EMC properties in measurements according to valid EMC Standards. Owing to use of a plurality of clock modulators along a course of a non-contacting rotary transmission path, signal jitter caused by individual components of the data transmission path is in each case replaced by artificially caused jitter of clock modulation. Thus, data transmission with defined jitter and defined signal quality can be achieved.
