基于TMS320F2808宽幅高频脉冲产生及测量系统设计

摘要

针对工程实践中同时产生宽幅,高频脉冲难的现状,以某航电模拟器为背景设计了一套宽幅高频脉冲产生及其频率、占空比测量系统,详细介绍了其硬件和软件设计方法并给出了实验结果.结果表明本系统产生宽幅高频脉冲方法简单,成本低廉,测量结果精度高,工程实践性强.%In view of the difficulty on generating PWM of wide amplitude and high frequency in engineering, a wide amplitude pulse-width wave generation and measurement system is designed for an avionics simulator,hardware and software are presented, and result analysis is also given. The system can generate wide amplitude pulse-width simply and costs low with high-precision measurement and strong engineering practicality.
