【摘要】 抗混滤波和频率细化（ZOOM）一直是数据采集和动态信号分析系统的两个关键问题和难点所在，本文介绍了采用基于数字信号处理器（DSP）的实时数字滤波技术实现这两种功能的原理和设计方法。结合自行研制的DTAS多通道动态测试分析系统，给出了这种设计的性能、特点及其应用实例。更多还原

【Abstract】 Anti-alias filter and frequency zoom are two key problems and difficulties of data acquisition and dynamic signal analysis system. This paper introduces the theorm and design method of DSP based real-time digital filters which can perform the two functions. With self designed DTAS multi-channel dynamic test and analysis system, the performances, features and application examples of this design method are given.更多还原
