Abstract: A transmitting apparatus of digital signals on a line (1) is disclosed, wherein there is a supply signal (Vbus) of electronic devices. Said apparatus comprises at least a direct-voltage switching converter (21) and means (3) suitable for varying the switching frequency of said converter (21) on the basis of a preset digital signal (Dig) to be transmitted; the converter is suitable for generating an alternating current signal (Salt) associated with the supply signal (Vbus) during the switching periods. The apparatus comprises further means (10) suitable for receiving said alternating current signal and suitable for processing the latter to obtain the preset digital signal (Dig).,1).
