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.
利用一個低通濾波器，提出混沌自同步的調制解調方法；
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.
採用光電傳感原理實現對液滴的測量，竝利用調制解調技術消除環境光乾擾。
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過VC編程實現用聲卡對信號的調制解調。
