<p>A system for providing information on the clock frequency of a data source in a digital receive-transmit system, where the clock frequency value of the data source is sent at a preset rate (FP), comprising a first signal (FS) at a first frequency (FQ1) associated with the data source, a second signal (FT) at a second frequency (FQ2) associated with the transmission system, measuring means for the first frequency (FQ1) of the first signal (FS) against the second frequency (FQ2) of the second signal (FT). According to the present invention said measuring means (CP, CN, CM) operates at a measuring rate (F) higher than the preset rate (FP) and a post-processing means (P) is provided to send a coded signal (U') to the receiver (R). <IMAGE></p> |
