摘　　要：本设计以实时采集血流多普勒信号并在PC机上显示为目的,使用单片机控制模数转换芯片ADC0809,采用单片机与PC机以串行通汛进行对话的方式,在PC机上显示采集到的血流多普勒信号的波形。The propose of this subject is real-time collection the Doppler blood velocity signal and displaying on the PC, and through a chip microprocessor controlling a A/D conversion chip ADC0809, and the chip microprocessor exchanges message with the PC by serial mode. At last the wave of Doppler blood velocity signal collected is displayed on the PC.
