Voice recognition applications requiring a superior user experience typically use a number of digital signal processing algorithms to filter, clean, and enhance microphone sampled audio. Frequently these systems will employ multiple microphones where more sophisticated algorithms can be used. These systems can leverage a Texas Instruments Digital Signal Processor to offload the complex real-time c - Dyamic Performance Testing of Digital Audio D/A ConvertersPDF, 145 Kb, File published: Oct 2, 2000
This application bulletin will provide the reader with an understanding of test methods for audio digital-to-analog converters (DACs). In particular, delta-sigma DACs require a special understanding due to the nature of their architecture.
