A bad radio transmitter design would produce adverse harmonic outputs which result in serious electromagnetic interference with other avionic equipment. The SR ( software radio) transmitter can meet different environment and demands of the users through the reshuffle application software, thus having very big flexibility. 一个设计不好的无线电发射机,工作时产生的谐波十分严重,而接收设备又对电磁干扰非常敏感。软件无线电发射机可以通过重配置应用软件来满足不同环境和用户的需求,具有很大灵活性。
