基于DSP和USB的信号采样传输方法研究

Research on Signal Sampling and Transmission Method Based on DSP and USB

通过设计一种基于USB和DSP高速信号采集系统,分析非均匀采样消除频率混叠的原理,阐述USB接口芯片的固件、设备驱动和用户程序开发过程。并通过实验验证所述方法的可行性。

A high-speed signal acquisition system based on USB and DSP is designed, This paper analyses the antialiasing theory of nonuniform sampling. The development of programming Firmware, device driver and user application of CY7C68013 are described, The validity of the method is verified by experiment.
