Abstract

A method to measure sampling jitter which might be generated by a digital-to-analog converter (DAC) or an analog-to-digital converter (ADC) while reproducing or recording musical signals is discussed. We propose a method to estimate waveforms of sampling jitter while reproducing or recording musical signals by some modifications to the jitter measurement which utilizes analytic signals. Computer simulations of the measurement revealed that the minimum detectable jitter amplitude was about 3 ns. Actual measurements of sampling jitter in the ADC and DACs were also conducted using the musical signal and a pure tone. And we have so far found no jitter components which are specific to the musical signal.
