| Abstract: | In order to achieve real-time data acquisition and process, a signal acquisition and process system was designed based on USB2.0., in which DSP (Digital Signal Processor) acted as the core. Utilizing the powerful data processing capability of DSP, this system can extract biomedical signals from weak signals and then analyze them. At the same time, it realizes a high-speed and dependable transmission of data between DSP and PC. |
