摘要
本文介绍了基于DDS技术的直升机超转信号发生器,同时介绍了DDS工作原理,设计了信号放大器和隔离功率输出级。此信号发生器输出信号频率误差小、分辨率高。
This paper introduces a helicopter over rotational speed signal generator based on DDS and introduces the principle of DDS,designes the signal amplifier circuit and implements the isolate output power stage.The signal generator shows good real-time performance on the least frequency error and high resolution.
