基于FPGA的4通道中频信号采集单元设计与实现

Design and Implementation of Four Channel Intermediate Frequency Signal Acquisition Unit Based on FPGA

针对舰船某控制领域应用较多的中频信号采集单元,采用以现场可编程逻辑门阵列(Field Programmable Gate Array,FPGA)为处理核心的技术方案,搭建前端模拟电路以及外围电路。该方案通过FPGA内部控制逻辑以及软核应用,实现信号采集、处理、传输等,验证了本设计方案的有效性。

The front-end analog circuit and peripheral circuits are built using Field Programmable Gate Array(FPGA)as the processing core for the Intermediate Frequency(IF)signal acquisition unit,which is widely used in a control field of naval vessels.The solution is validated by the internal control logic of FPGA and the application of soft core to realize signal acquisition,processing,transmission,etc.
