SAMPLE RATE CONVERSION METHOD AND APPARATUS

摘要

An arbitrary sample rate conversion apparatus is described. This apparatus includes a buffer (10) for forming blocks of input samples having a first sample rate. For each block of input samples a subfilter is selected from a polyphase filter (18). Means (12, 16) are provided for block convolving each block of input samples with the corresponding selected subfilter for producing blocks of output samples having a second sample rate.
