Abstract:
1. A device for filtering electromagnetic interference generated by an antenna ( 20 ) of a transmitter on a sensor ( 30 ) sensitive to electromagnetic waves, characterized in that it comprises in particular: i. means suitable for sampling an signal (SN ii. means making it possible to count down an elapsed time, called the detection time, after a sampled signal has exceeded a threshold value (S), said signal, before exceeding the threshold value (S), being in a range of standard values, iii. means making it possible to compare in real time a detection time with a threshold time value (T iv. means suitable for providing a diagnosis of electromagnetic interference to be filtered if the sampled signal reverts to a standard value after a detection time of less than the threshold time value (T v. means for generating an output signal (SN
