Demo system of amplitude modulation based on Java

Demonstration system of amplitude modulation based on JAVA is developed. First, this paper analyzes the principle of amplitude modulation and demodulation. Then, The Architecture of demo system is designed. According to function requirement, we adopt object-oriented method to design and implement the demo system. Finally, we use the button to debug the demo system. The results indicate that the signal wave can change with pressing the button. The demo system has an attractive interface, and is convenient to operate. It also has a good interactivity. This demo system has already been used in educational practice and got a good effect.
