| Abstract: | A high-speed data acquisition system based on FPGA for acquiring echoing signals of uniform transmission lines is designed and implemented with C8051f020 as the main controller, FPGA as the high speed memorizer, and FLASH chip of ad9054 as high-speed ADC. Through experiment, the phenomena of time delay and reflection of traveling wave process is observed. |
