摘要
开发了一组高性能的数据采集和处理模块，叙述了这种采集处理模块如何有效地用于主动声纳接收机中。由于Ｓｉｇｍａ－Ｄｅｌｔａ结构的基本采样特性和完善性能，这种基于Σ－Δ结构的采集处理模块十分适合于声纳和其它音频的实时应用。
Using TMS320C40 DSP device and Sigma Delta converters, this paper develops a high performance card set for data acquisition and processing in sonar systems. Ways are described in which such card can be efficiently employed in active sonar receivers. Due to the sampling features and high performance of the Sigma Delta architecture, the card proves suitable to real time applications of sonar and other audio systems.
