Sample rate conversion method and apparatus |
摘要 |
An arbitrary sample rate conversion apparatus is described. This apparatus includes a buffer 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. Each block of input samples is convolved with the corresponding selected subfilter for producing blocks of output samples having a second sample rate.
