Abstract :
This paper describes a novel precision audio measurement instrument, the Data Converter Test Module (DCTM), which utilizes a “two pass” measurement technique for the precision measurement of AC sine waves. The two-pass technique can measure near -140dB THD in less than 20ms in a production environment.
