【摘要】 时间延迟谱技术(TDS)是一项较新的测量技术,它可以用于测量电声系统的复频响应和复时域响应。本文讨论了TDS的一些基本概念和一种简化的实现方法并给出了一个具体的测量系统。该系统由本文作者设计,它以一台IBMPC-AT为核心,软件为主体,具有丰富的测量功能。最后,本文给出了一些测量实例以演示和验证这套系统的功能。更多还原

【Abstract】 Time Delay Spectrometry (TDS) is a new measuring technique which can be used to measure the complex frequency response and the complex time domain response of the audio system. Some basic concepts of TDS and a simplified method of realization are discussed and a measuring system is given in this article. Further more, this designed system consists of IBM-PC as the core and the software as the main substance with multifunctions. Finally, some examples of measurement are presented so as to demonstrate and verify the capabilities of this system.更多还原
