论述了PDM2000-Ⅱ型数据采集与分析仪的数字信号处理板的设计过程。硬件设计讨论了基于TI公司的TMS320C31的设计，包括A／D的连接，存储器的扩展，总线的控制，以及程序引导装入功能的实现。软件设计讨论了实时抗混叠数字滤波器的软件实现及应注意的问题，FFT实现中应注意的问题。
Discusses PDM2000-Ⅱ data acquisition and analyzer digital signal processing board design process. The hardware design discusses the design of the TMS320C31 based on TI, including A / D connectivity, memory expansion, bus control, and program bootloader functionality. Software design discusses the real-time anti-aliasing digital filter software implementation and should pay attention to the problem, FFT implementation should pay attention to.
