Abstract

Multirate digital filters are employed in DSP based receivers to change samples of an asynchronous input data stream to samples of a synchronous output data stream. This process is managed by controlling the phase offset of a concurrent up and down sampling operation in a polyphase filter bank or by controlling the phase of a down sampling polyphase filter operating on an over sampled input time series.
