| () |
| Abstract: |
| The design method of a digital signal processing platform for high-speed wideband sampling is introduced.How to design the high-speed synchronization clock and high-speed data synchronization receiving in Xilinx's V4 FPGA is analyzed.The high speed analog/digital(A/D) mixed circuit design and data capturing method after sampling are also introduced.This scheme has been used in the instantaneous frequency measurement,and the platform works well. |
| Key words: wideband sampling,synchronization clock,high-speed data,synchronization receiving,analog/digital(A/D)mixed circuit |
