modulation-demodulation method

基本解释

With a nonlinear low-pass filter, a method of modulation and demodulation is discussed in self-synchronizing chaotic communication systems.
利用一个低通滤波器，提出混沌自同步的调制解调方法；
The system could detect the drops of liquid through the transfer line with optic-electric detect technique. The interference from light around is reduced using the modulation-demodulation method.
采用光电传感原理实现对液滴的测量，并利用调制解调技术消除环境光干扰。
The research method is using VC programming to realize the modulation and demodulation of the signal by audio-card.
本文研究的方法是通过VC编程实现用声卡对信号的调制解调。
