Abstract:
1. An arrangement for synchronizing a signal processing apparatus with a received signal which has a characteristic signal content appearing at a position and an associated appearance time, the arrangement comprising: a flow control device; a first control loop configured to readjust the signal processing apparatus with respect to the characteristic signal content on a content basis; a second control loop configured to readjust the flow control device in the signal processing apparatus with respect to the times at which the characteristic signal content appears; wherein the first control loop and the second control loop are independently operating control loops; wherein the first control loop and the second control loop are coupled such that a unique association is achieved between the position of the characteristic signal content in the received signal and the associated appearance time, wherein the received signal has samples which are arranged at a particular distance from one another, and wherein the first control loop and the second control loop are coupled via a variable fractional sampling rate conversion device comprising at least a data capture device and a sample counting device configured to change the distance between the samples in the received signal on the basis of a conversion ratio to generate a converted received signal having the characteristic signal content from the received signal, said variable fractional sampling rate conversion device configured to perform time compression or expansion for signal contents so that an operating clock for the arrangement can be based on different frequencies.
