Method for suppressing interferences in a sampling process as well as a device for carrying out the method

A method for suppressing an interference in a sampling process, comprising:

• sampling an analog useful signal at a sampling frequency f;
• determining whether an interference amplitude is present;
• in the presence of an interference amplitude, stochastically shifting chronologically equidistant sampling points in time, which are determined by the sampling frequency f, within a range [−Δt;
• +Δt] around the equidistant sampling points in time, At being a maximum shift;
• resampling the analog useful signal;
• redetermining whether an interference amplitude is present;
• in the case of a continuous presence of an interference amplitude, changing an absolute value of the maximum shift |Δt|;
• and
• restarting with the method step of stochastically shifting the sampling points in time.

A device for suppressing an interference in a sampling process, including:

• an arrangement for sampling a useful signal at a sampling frequency f;
• and
• an arrangement for determining an interference amplitude and determining whether the sampled useful signal is acted on by an interference amplitude, wherein the arrangement for determining the interference amplitude stochastically shifts, in the presence of an interference amplitude, chronologically equidistant sampling points in time, which are determined by the sampling frequency f, within a range [−Δt;
• +Δt] around the equidistant sampling points in time, Δt being a maximum shift, and wherein the arrangement for determining the interference amplitude resamples the useful signal at the stochastically shifted sampling points in time, and changes an absolute value of the maximum shift |Δt| in the case of a continuous presence of an interference amplitude.
