ABSTRACT:
The present invention relates to a method and a device of information transfer between two circuits exchanging data via delta-sigma converters. The present invention includes coding the information in the form of at least one signal of determined frequency corresponding to an integer multiple of a frequency of the digital data samples; mixing, at a first end of a line carrying an oversampled digital signal of the converter, the signal of determined frequency; extracting from the mixture, at a second end of the line, the signal of determined frequency; and decoding the corresponding information.
