Abstract:
1. A device for controlling an absolute transmission time of a continuous transmission signal in a transmitting/receiving unit comprising: a correction unit configured to produce an output data signal based on a received correction signal, wherein the correction unit comprises a fractional sampling rate converter unit comprising a variable sampling rate conversion ratio, wherein the fractional sampling rate converter unit comprises a first input configured to receive an input data signal having an input sampling rate, and an output configured to output the output data signal having an output sampling rate, and a second input configured to receive the correction signal and adjust the sampling rate conversion ratio thereof based on the correction signal, a sequence control unit connected downstream from the correction unit and configured to produce a working clock signal, a counter unit electrically connected to the sequence control unit and configured to use the working clock signal from the sequence control unit to generate an internal actual transmission time signal, and a control device configured to compare the internal actual transmission time signal with an external nominal transmission time signal to produce the correction signal, and further configured to transmit the correction signal to the correction unit in order to correct the actual transmission time.
