  • Sample rate converter
    Patent number: 6590510
    Abstract: A sample rate conversion method and apparatus is disclosed to convert an input data stream having an input sample rate to an output data stream having a desired output sample rate with a preselected accuracy up to a given band limit, comprising constructing a cascading filter system of one or more stages, each stage having one or more filters, and each filter having a filter length such that the cascading filter system meets the preselected accuracy of the desired output sample rate, wherein each filter is constructed in the space of band limited functions, and convolving the input data stream with the cascading filter system to generate the output data stream with the desired output sample rate.
