Method and circuit for converting the sampling frequency of a series of samples avoiding conversion into a continuous signal

Abstract

Abstract An input sampling sequence with an input sampling rate is translated into an output sampling sequence with a selectable output sampling rate in a sampling filter. A circuit for forming the time difference of the sampling points forms from the given input sampling rate and the desired output sampling rate a signal corresponding to the time difference and this is used in a translation circuit for converting into data for characterizing the filter coefficients. The sampling filter is conditioned by the selected coefficients from the translation circuit. The invention is suitable for the transmission of sampled data, particularly sampled rates between two systems operating at different clock frequencies.
