Abstract In this paper a sample rate conversion algorithm which allows for continuously changing resampling ratio has been presented. The proposed implementation is based on a variable fractional delay filter which is implemented by means of a Farrow structure. Coefficients of this structure are computed on the basis of fractional delay filters which are designed using the offset window method. The proposed approach allows us to freely change the instantaneous resampling ratio during processing. Using such an algorithm we can simulate recording of audio on magnetic tape with nonuniform velocity as well as remove such distortions. We have demonstrated capabilities of the proposed approach based on the example of speech signal processing with a resampling ratio which was computed on the basis of estimated fundamental frequency of voiced speech segments.

In this paper the polynomial approximation of the transfer function of an analog-to-digital converter (ADC) affected by harmonic distortions is investigated. The theoretical expression of the polynomial approximation of the transfer function of an ADC with harmonic components up to 5th order in the case of a sine wave test signal is derived. Also, a practical method to determine the polynomial approximation of an ADC is proposed. The simulation effected confirmed that the results obtained by this method are very accurate. Moreover, an ADC test system, developed to determine the polynomial approximation of the transfer function of an ADC by the proposed method is presented. Some experimental results obtained with this test system are given.
