Abstract
Sample values of a digital signal of a first sample rate are supplied to a digital filter for conversion into a digital signal of a second sample rate. The coefficients of the digital filter are calculated by a processor from the ratio of the sample rates or are obtained by a read-only memory containing sets of coefficients for respective sample rate ratios for which the apparatus is usable. Filtered sample values are read out of the digital filter at the desired second sample rate. A buffer memory is used at the input of the digital filter and a regulator is provided to prevent fluctuations in the filling of the buffer memory from emptying or exceeding the capacity of the buffer memory.
