Abstract :
The paper describes some new research results from designing analog-to-digital conversion for audio measurement system using MLS (maximum length sequence) algorithm. Evaluation version of USB audio measurement interface with two types of high quality analog-to-digital converters (ADC) has been presented in the paper. Comparison was subjected to 16 bit ADC with one bit sigma-delta (SD), fourth-order modulator and 16 bit SAR (successive approximation register) ADC. Superior performance of the SAR analog-to-digital converters over sigma-delta ones has been shown.
