Title: Shift-invariant digital sampling rate conversion system

Abstract: There is described a method of making a linear periodically time varying system shift-invariant, comprising the following steps implemented for each input signal the sampling rate of which has to be converted: --generating a set of polyphase components based on the input signal, --feeding the generated set of polyphase components to the system, and --generating an output signal by performing interleaving, shifting and addition on signals output by the system corresponding to the generated set of polyphase components processed by the system.
