摘要
本设计利用FPGA作为数据处理和系统控制的核心,通过FPGA及其外围电路完成脉冲信号参数的测量。其中外围电路由信号前置处理模块、双路比较器模块、显示模块等模块组成。经前级电路处理后的信号送入FPGA,利用FPGA较强的信号处理能力完成对信号的测量,最后由LCD显示屏显示参数。在实际应用中具有体积小、实时性好、工作效率高等特点。
In this project,we use FPGA as the core of data processing and system control to complete the measurement of pulse signal parameters through FPGA and its peripheral circuit.The peripheral circuit is composed of several modules such as signal preprocessing module,dual-channel comparator module and display module.After the processing of the pre-stage circuit,the signal is sent to FPGA and then measured by its strong signal processing ability,finally the parameters are displayed by the LCD display screen.In practical application,it has the characteristics of small volume,good real-time performance and high efficiency.
