Abstract
A device for processing a digital signal includes a Farrow structure () that applies to the digital signal a time-varying sample rate conversion from the fixed sample rate to a time varying sampling. The digital signal sampled at the time varying sampling is a resulting signal. The Farrow structure () is controlled from a control variable. A spectral analysis means () performs a spectral analysis of the resulting signal to determine the frequency values of the resulting signal. A determining means () determines a sparseness parameter of the frequency values of the resulting signal. A controlling means () modifies the control variable according to the value of the sparseness parameter.
