  • Efficient two-stage asynchronous sample-rate converter
    Patent number: 9258011
    Abstract: Methods and systems consistent with the present invention provide an improved sample-rate converter that overcomes the limitations of conventional sample-rate converters. The improved system comprises a simple asynchronous sample-rate converter and synchronous sample-rate converter. The output of the simple asynchronous sample-rate converter is connected to the input of the synchronous sample-rate converter. In an alternative embodiment, the output of the synchronous sample-rate converter is connected to the input of the simple asynchronous sample-rate converter.
    Type: Grant
