Amplitude modulation and demodulation circuit 振幅复?调回路
An adaptive demodulation circuit is also given to reduce the affection of the noise , the interference and the instability of the signal 目前,采用自适应检波电路的处理机己经在工业用避碰雷达中获得应用。
The thesis studies the principle on the ppm modulation and demodulation , and analyses the performance of the ppm signal demodulation circuits and designs corresponding circuits 研究了ppm调制与解调原理,分析了ppm信号解调电路系统性能并进行了电路设计。
It is comprised of short message processor and tfaas application . the former is concerned on software for at89c51 and other hardware which include fsk demodulation circuit soft keyboard circuit and so on 短信处理器由89c51软件和相应硬件组成,包括fsk解调电路、软键盘电路等。 89c51软件主要完成短信接收和分析并将采集数据进行发送。
