Abstract
A sampling frequency converter converts sampled input data having an input sampling frequency into sampled output data having a different output sampling frequency. The relative ratio between input data sample periods and output data sample periods is determined and averaged over a predetermined duration. A filter coefficient generator responds to the averaged input/output sampling period ratio for generating data representing a set of predetermined filter coefficients which are used by a sampling filter circuit to convert the input data samples into output data samples of a different sampling frequency.
