A method and apparatus are described for asynchronous sample rate conversion, in particular those which use an interpolating filter, especially a polyphase interpolating filter (FB 4 ). The input and output signals have jitter but the polyphase branch signals have no or reduced jitter due to the operation of a jitter removing means such as a phase locked loop. The jitter is reduced only in the polyphase branch signals. Various methods are described for reducing the jitter.
