作者一直在研究推广Shannon抽样定理的流利信息理论及其应用。在研究的实际应用中，作为CD音频的数模转换器而开发的Fluency DAC获得了客观的评价，包括1988年的金音奖。最近，出现了处理最大采样率为192 kHz的DVD音频。由于DVD音频的引入需要四倍于当今CD音频的采样率，因此开始要求开发用于DVD音频的新Fluency DAC。从这样的需求出发，我们开始了对DVD音频流畅度DAC的研究。研究结果可能会使2000年和2001年日本音响设备本地比赛的奖项复活。作为我们在开发能够处理最大采样率为192kHz的Fluency DAC项目的初步报告，在本文中，我们的目的是推导出作为这种D/A转换器的脉冲响应的采样函数。
Authors have been studying Fluency Information Theory that generalizes Shannon’s sampling theorem and its applications. Among the practical application of the research, the Fluency DAC that is developed as the Digital-to-analog converter for CD audio could have received objective valuation including receipt Golden Sound Award in 1988. In recent, DVD-Audio that deal with maximum sampling rate of 192 kHz has appeared. Due to the introduction of DVD audio that requires four times the sampling rate of nowadays CD audio, the request for developing a new Fluency DAC for DVD audio was initiated. From such requirements, the research for developing the Fluency DAC for DVD-Audio has been started. The result of the research could revive awards in local contest in Japan audio apparatus at 2000 and 2001. As the initial report on our project in developing the Fluency DAC that is capable of dealing with a maximum sampling rate of 192kHz, in this paper we aimed to derive the sampling function that acts as the impulse response for such a D/A converter.
