Design and implementation of delta modulation based on Java

In order to demonstrate delta modulation principle, A delta modulation system Based on Java is put forward. First, this paper analyzes the principle of delta modulation and quantized noise. Then, The Architecture of delta modulation system is designed. According to function requirement, we adopt object-oriented method to design and implement the delta modulation system. Finally, we use the button to debug the delta modulation system. The results indicate that the signal wave can change with pressing the button. The delta modulation system has an attractive interface, and is convenient to operate. It also has a good interactivity. This delta modulation system has already been used in educational practice and got a good effect.
