A SAMPLING RATE CONVERTER USING DISCRETE-TIME FEEDBACK

Abstract

The sampling rate converter (SRC) is used when systems operating at various sampling rates are connected to each other. In order to obtain high signal-to-noise ratio (SNR), especially in systems with random and time-varying sampling rates, SRCs using conventional DSP approaches are very difficult to be designed and manufactured. This paper introduces the SRC using discrete-time feedback. Theoretical analysis and simulation results presented in this paper will illustrate the advantages of this new approach over the conventional DSP algorithms used in the SRC.
