Abstract:
Audio Measurements
Audio equipment with sigma-delta converters and class D switch-mode amplifiers can present problems to audio analyzers. A practical solution to strong above-audio band frequency components using a controlled bandwidth analyzer and a simple RC filter are demonstrated. Analog / I2S performance measurements are explained and demonstrated.
