中文摘要	A digital system for ultrasonic signal acquisition and processing is provided in this paper. Ultrasonic echo signal is digitized with a high speed and high resolution AD converters, and then processed in a field programmable gate array (FPGA) chip. Through USB 2.0, demodulated signal is transferred to PC, in which post-processing is carried out and final results are displayed. As an example, the results from a simulated blood flow measurement are provided. Compared to the conventional analog systems, the proposed system is more stable and flexible, and could be applied in various ultrasonic signal acquisition and processing.
