摘要
本文旨在介绍了一种利用锁相环路与大规模集成电路相结合,产生多种数字调制的电路,且可将方波信号变为模拟正弦信号。实验结果表明:该调制方式输出频率稳定,旁瓣分量小,满足传输要求。
The paper tries to introduce a new circuit which can realizes multi-mode digital modulation using the phase-locked-loop and large scale integration and turns square wave signals into sine wave signals. Experiment shows that the out frequences are very stable,sidelobe compoents are small and are suitable for transmission.
